nicecook Thanks for sending us your skeleton files! We'll check to see if we can reproduce the problem, but just to let you know, you seem to be using Spine 4.2.22 to create your skeleton, so I'd like to let you know that you should be using the latest patch version of the editor.
Updating to the patch version is always safe, and there are many bug fixes between 4.2.22 and the latest version (4.2.40), so please update your editor.
