Slim skin bug

Hello! This is a strange bug that has only become a big problem sense the latest update ok so whenever I choose my skin (import one from my photos) it will say there a slim model I can pick but is invisible- this doesn't effect gameplay tho just seems like visual bug in the on the skin thing. Whenever I pick the slim skin and then go into a world it still shows the skin so not a big issue. I had a similar bug in the update before the latest where the skim model would invert the leg texture- but only on one leg...anyways here's some photos of the new bug! Hope this will be fixed! Thanks!
