Occult Sims in human form perform their idle animations and sounds in CAS

All occult Sims in CAS perform their specific idle animations or sounds even when they are in their human (non-occult) form. This happens to all occult Sims while in their human form in CAS, including werewolves, spellcasters, mermaids, aliens, and vampires. I do not use mods, and I have all DLC except the 13 Maker Pack.
