Short description of error
whenever you eliminate one or more complete animations, orphaned keyframes remain, and I have never found a way to eliminate or clean them, nobody knows how to do it, they always tell me to make a new blend.
Exact steps for others to reproduce the error
create keyframes for animations and then delete them, and almost always there is a keyframe that can not be deleted.
here is the file with a keyframe that can not be deleted
