You aren’t supposed to be able to run v7 and v8 alongside each other, so how are you managing to drag tracks from one to the other?
I assume John is dragging audio and midi stems from a Windows folder into v8. I’ll give it a try later and see if my experience is similar.
Perhaps it's different in Windows, but I can run PreSonus Studio One 7.2.3 and Fender Studio Pro 8 at the same time on the Mac with no problems, at all.
On the Mac, they are
separate and
independent applications, complete in what for macOS are called application packages (a.k.a., UNIX "bundles") and have their own resources and everything else.
Among other things, this is the reason you need to keep a copy of your user-defined custom templates; because at least on the Mac, installing an update or new version probably will overwrite the resources and everything else in the "bundle", including any user-defined custom templates you might have put there. Perhaps not, since I have not determined where the user-defined custom templates are stored; but it works this way with NOTION 6 on the Mac; so it's best to have your own copy of your user-defined custom templates. at least as a backup or archive.

Regarding "dragging audio and midi stems from a . . . folder", this is
not something I do, although it apparently is possible, at least to some degree.
I will try it and see what happens.
For reference, I am not suggesting stuff like this is illogical or makes no sense; but it's not something I do or even need to do.
I did some scouting around, and there is a "Media" folder and a "History" folder in the song folder; but I don't use them or even noticed they were there until this conversation.
On the other hand, there is an "Export Stems . . . " menu item; but I have not needed to use it. I have at various times used the "Export Mixdown . . . " menu item, but at the moment I forget why. Perhaps it was when I captured the audio for my favorite Rammstein song, "Radio" and was trying to get it into Audacity to slow it down enough to decipher Flake's stellar synth phrases in the Intro, which continues to elude me.
It's stellar, but it's sufficiently chromatic in a "tight" way to make no intuitive sense to me.
If I listen to the song enough times, perhaps I will be able to identify the notes . . .
EXPERIMENT
I did a quick experiment and dragged a WAVE file from the "Media" folder into a new Fender Studio Pro 8 song, and the audio clip was pasted but not the various VST effect plug-ins.
Then I closed that song and opened a song that has a MIDI sequence for an electric guitar and then exported it as a .MID fie using "Export Selection" as described in the Fender Studio Pro 8 "User Reference", which as with all such tomes I make an effort to avoid reading.
Then I dragged-and-dropped the .MID file to an empty Fender Studio Pro 8 song; and it was pasted but there was no corresponding Instrument Track and none of the VST effect plugins. The MIDI sequence was there, but there was no way to play or hear it, and there was no Instrument Track for it.
So, I created an Instrument Track with a SampleTank 4 (IK Multimedia) electric guitar and then dragged-and-dropped the MIDI sequence from where it was onto the new Instrument Track, and then it played, but there were no VST effect plug-ins and no Automation curves for it.
From this experiment, I infer that if it used to work, then it doesn't work now in Fender Studio Pro 8.
Yet, I can see how it might be useful to grab a MIDI sequence and then to use it to play another virtual instrument on a different Instrument Track--for example to use a MIDI sequence for a violin to play an oboe or something similar, although it's not something I have done or even thought about doing.
However, since I do everything in music notation, I have copied measures of music notation and then pasted them to other staves, but there is no specific exporting and importing, as fart as as I know.
SUMMARY
I was able to reproduce what the OP described colloquially as a "mess"; and if it ever was working, then it's not working in Fender Studio Pro 8.
It's also not something I plan to do, because "Import Session Data . . . " is what I use; and it's one of the things I
like about Fender Studio Pro 8 and use every so often when I want to add something I already created and fine-tuned in another song.

NOTE: "Radio" (Rammstein) is one of my current favorite songs and Christian "Flake" Lorenz's synth is making me crazy; but I will decipher the notes, eventually, where for reference it's just the rapid notes, because the other stuff is easy to discern. For reference, the song is about East Germany when the only way to get information about the world was via the radio. Radio was very important, especially for music in East Germany. This version has English lyrics. ]
