In previous versions it worked totally as I expect. It started works that strange way only in latest versions of Spine. I do not consider it a normal behaviour. It really impacted my workflow in a bad way.
How can I select only Translate (blue ones) keys? There is literally no way other than selecting keys one by one or excluding other bones.
I think you didn't understand me. When I select ALL keys applied to the bone, upper keys will also became selected and it's OK. But now GREEN keys become selected even when I select ONLY BLUE ones.
