Unfortunately, time does not allow us to verify what you are asking.
If there is free time, I will ask the animator to correct these moments, if he wishes.

But it would be interesting for me to find out if the problem is really in the errors of the Spine project.
Because it came to me on the go to supplement the plugin written by me for more convenient use of Spine in unity
