Changing werewolf form also changes sim's face

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? SP26: 1.assets.ml-sp26.38
What expansions, game packs, and stuff packs do you have installed? All of them
Steps: How can we find the bug ourselves? Go into create a sim with a sim that has been turned into a wolf (not created as a wolf, an already existing sim being bitten, then taken into cas) and then change the wold form. For me it happens when when I change the ears.
What happens when the bug occurs? I go into CAS to change my sim's wolf form. When I click on ears, the sim's real face (sim/human face) changes, makes her jaw really wide and her eyes bigger and more together. I thought it was cas or mods (I had mccc and some clothes) so I removed it all and tried to change the wolf, and it still happened on my vanilla game.
What do you expect to see? I expect her human/sim face to stay the same even if I change her wolf form
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

So, My sim got bitten - I went into CAS to change the wolf form. I went to change the ears on the wolf form and it changed my sim's actual face.
