Sims 4 Studio Geom data files are missing

I was working on a piece of CC, attempting to make it transparent. I noticed that when I go to make a new package, my geom data files are missing. I don't have this issue with any of my previous files or my custom content, just all of the game stuff that seems to not be working. The problem is only fixed if I export the base mesh and then re-import it again, save it and then open it again. However, I do not want this to be apart of my routine when creating.
