"Transform to Rendered Audio" used on Bus-Folders looses all layers in contained tracks!!!

[Wolfger]

I already knew that using "Transform to Rendered Audio" on tracks one looses all the layers of those tracks when "Transform to Realtime Audio" again.
We already discussed this in another thread.

But today I discovered, that using "Transform to Rendered Audio" on Bus-Folders looses all layers on all tracks contained in this folder when "Transform to Bus Channel" is applied.
That´s a major concern to me. I think this needs a fix!

Any opinions?

01) Two tracks in a Bus-Folder, each with 2-3 layers

02) "Transform to Realtime Audio"

03) "Transform to Bus Channel" ----> All layers gone!!!!
