Can't change ghost colours

Hi everyone,

I hope someone can help me out here. I've been trying to change the colour of my ghost, but when I try to click on the option 'Change Ghost color' on my sim (which is there), it doesn't look at all like how it looked during the streams, instead I get this: 

Which also won't go away. I cannot seem to be able to figure out how this is possible. I just want to change my ghosts' color :( IS anyone able to help me please? 

Kind regards
