UPDATE: I downloaded an update last week that has corrected this issue. Adobe called me to confirm the fix. Really appreciate the quick fix and the call. Nice work!
Fixing the major issue has cleared the way for noticing other problems with mono split tracks. Two things remain a glitch:
1. Audio still randomly drops out.
2. If I apply a default crossfade to split mono tracks I get a random glitch sound that spikes really loud. Sometimes it's a small hit and other times it lasts the entire duration of the crossfade.
