My sims turned pitch black while wearing custom tattoos

Hi! When I logged into my game and went into live mode, I noticed that my two sims with tattoos were completely black with no depth. I assume it’s because of the new tattoo feature since both my pet and my sims that I painted on were like this. Please fix this, I really enjoy the new custom tattoo feature and I would like to actually use it since I payed for it. 
thank you in advance.
