V15b7 - Audio bug in Edit - Audio plays when there is none

I have an odd bug in the new v15b7, in that I have audio playing when there is none on my timeline.
For example, I have audio on tracks 3 and 4 and none on tracks 1 and 2, yet random audio from a different part of the project plays, and the mixer says it's coming from track 1.
Also, Resolve has seen fit to rename my audio tracks as Audio 4, Audio 13, Audio 3, and Audio 4 (again!).
