Short description of error
In the Dope Sheet's Action Editor I have some keyframes which are yellow even when they are not selected - even deleting them does not make them go away. The keyframe that shows on the Summary line does go away, but not in the bone channel.
Exact steps for others to reproduce the error
I linked a character rig, made it into a proxy, created an action and started animating. I am not sure what exactly caused it - though I suspect maybe it has something to do with copy and pasting keyframes, including using "paste flipped". For example, I first started noticing something was wrong after rotating 1 arm bone (auto key on), moving ahead and then pressing Ctrl-Shift-V to paste flipped and rather than pasting onto the opposite arm it messed up the currently select arm. Yet if I deselect all bones (Alt-A) then Paste Flipped, it works correctly. I'm not sure if that is expected behavior (I hope not), but shortly after that I noticed the glitched keyframes that wouldn't deselect or be deleted.
