Hi!
PNG export is creating extra folders, each time with ".png" in the name but not naming the i
I recorded a video about what I experience
current pose PNG export is working wierdly
It's strange you see Maximum bounds. That doesn't show for me in the same situation (multiple skeletons with all but one hidden).
I'm unable to get 4.2.42 to create a folder from the output file path.
If a folder with the same name as the PNG is in the way, the path updates to append the skeleton name. If I enter a path, then put a folder in the way, it exports into that folder using the skeleton name. Neither of those is what you see though. I see you specified a path, no folder was in the way, and it created a folder for some reason. It's hard to fix when we can't see the problem. 
Can you please click Save in the bottom left and post the export settings JSON file?
hi Nate!
I exported a jeason I imported back, and now I can export PNGs normally:
But I do not understand why I can export form a standard project, properly. (it is not just this one but any project which I open from spine file, or I create from scrach)
I ZIP-ed everything I am curious if you can experience the same thing with my file:
