Thank you very much, that is indeed interesting.
Can you please check if the post type name is not within this list: https://i.imgur.com/L1mviyz.png
If it’s there, then please try removing it. Then the plugin should correctly determine to not to load that stylesheet file there.
I also checked those CSS rules, those should not be there anymore, as they were depricated. I will make sure to remove them in the upcoming release.
