Some Tracks Moving When Pasting

I use Audacity for recording songs. I will sometimes insert different tracks (like cymbals, or drum fills) into certain spots in the track. With this latest update, I paste the new track in but then other tracks move backwards which has never happened before. The tracks that seem to move are ones that I’ve split previously - they move to the end of the track (or to the end of the pasted section in the timeline.
Not sure if I’ve explained that very well but this has happened before.

I can’t believe this isn’t happening to anyone else. How does Audacity support work?

Never mind. I’ve now rolled back to 3.6.1 where the track moving wasn’t an issue.
