Dark form changes human form in CAS

I’m talking about my vampire sim. It has a human form and a dark form. I guess human form is what it’s called? Maybe not, lol. Maybe it’s just it’s nice form? I’m not sure really how to explain it other than my vampire sim has 2 forms. One I know is called a dark form because I have the option to “show” and “hide” dark form. The other form is what my sim is in normally. What she looked like before she was turned into a vampire.

anyway, when I go to edit her outfits via the dresser it defaults all her looks to the human (or “regular” whatever it’s called) form. So I went through and changed it all how I wanted it and then above her picture in CAS mode I can click her dark form to edit it. So I do that. But as soon as I make a change it changed her human (or regular, or whatever it’s called) form Into her dark form (as shown in the photo I attached).

I don’t have any mods. After I added my CC and applied it to my sim everything worked fine. It wasn’t until after the update that I had this issue. So I removed all CC from my game thinking it was that. I know it’s all removed because I don’t get the mod message at startup and I get the “sims items were removed because You don’t have them or EA doesn’t have them” message and everything I had CC for is gone.
