This is actually making me feel like I'm going crazy. I've expanded my audio tracks to see the "Audio 1" title.
I right click and choose "Rename" and it allows me change the name.
I change the name to something like "Character 1 Lav"
It appears like it should.
I scroll down the timeline, change the track size or pretty much do ANYTHING and the track names either shift down to the one below it so now A2 is named "Character 1 Lav" or it just resets completely back to "Audio 1".
This is after several restarts, reboots and different edit sessions.
