I am seeing this on PS4 to a point. I can assign male vampires to a bed but not the female ones. Then when the female goes to use the "sleep" interaction on the bed it says "This is Male Sim Name's Bed!" and doesn't assign them to the bed until they sleep in it but the message remains when selecting the sleep interaction. These screenshots are from subsequent loads to the household so the female appeared.
I also am not able to assign vampires to computers or doors. The whole household doesn't appear in the windows. Only 2 of the 5 showed up here on the door lock, computers and beds.
The next time I loaded their household, three of the sims appeared in the list.
Turns out I may have had the same problem as PoptartJuniper in my mod test save last year, as the screenshot I attached shows (only Caleb showed up in that list...I think I was assigning his bed there, but when I tried to assign Lilith her bed in her room afterwards, she was absent from the picker window).
They don't have this problem in my main save so far, but that's apparently because I had them claim their respective beds long before the DU patch.
