Why is some of my Cc showing up as Alien Clothing ?

Hi all, Sims 4 Studio has added a batch fix feature that scans your Mods folder and fixes all the alien catalog thumbnails so they'll show up with the original catalog thumbnail the item had. It's easy to use and won't change anything except what's needed to get rid of the alien thumbnail. The feature has been tested by lots of people and works well :)
