Thanks, I tried ungrouping but that didn’t do it - however I just found this as a reply from 9 years ag that fixed the issue (must have mistakenly hit “K”), and since it’s unclear which version of Cubase - I didn’t find the “=” symbol, it still worked.

Finally sorted this!!!
Actually on reading again, the clues are above, but with subtle differences.
I was trying to recreate and noticed that this happens in some songs and not in others at all. All my tracks are in groups - one group for VSTs, one for external hardware, so on… Somehow I had pressed the K key which turned on grouping for the whole group ie all tracks!
The only visual clue is an = button on the group lane itself in the inspector and the group lane becomes dotted out. From then on all parts of the same size seem to group in this way.
Press K again (or click the = button) and its gone away!
HTH somebody.
