Short description of error
I get this bug very often but I still haven't been able to find the trigger, and I've been noticing it since March.
If I set a strip to Hold, it'll eventually revert to Hold Forward, it's a mystery how or why though.
I usually only use Hold on strips at the beginning of a track, this might be a condition for the bug, I'm not sure.
If I set the extrapolation to Hold Forward or Nothing, it doesn't revert to another mode.
