Last night after doing quite a lot of edits, mainly adding midi and audio tracks, when i did undo twice with nothing in between, the track names got mixed up, as used to happen before the update.
I have not got full repro steps as I had done a lot of work. What I can tell you is the names got messed up after the second of the 2 undo steps I performed. The first undo was a transpose done in the midi edit window. The second undo was a track rename.
