Details as to recurring bug... I'm unable to pinpoint how it starts (but it never fails to reveal itself at some point while I'm working). The gist is there's an additional frame that shows itself where her arms in the left window aren't raised. The animation should just be her repeatedly jumping with the bells above her head). At some point, while re-playing highlighted portions of this specific animation in the central layer (where you see me highlighting frames), her arms lower for one frame.

The source of this frame I think lies in the frame group before it, where her arms are by her side instead.

That frame shouldn't visually show up when you place a hold frame (the blank boxes), as they stop the last frame from repeating or effecting anything after it.

And they don't show when I'm using my arrow keys to go through each frame manually. It's only when I auto-play the frames that it shows itself.
