I would just make sure that when you are entering in custom descriptions, don't add them all at once; What i mean by that is for instance, if you are trying to describe your "face" using the descriptors "beautiful, stunning, exotic" each one has to be entered separately for the game to see them as separate descriptors. If you enter them in all together, the game treats it as a complete string and will use the entire string, which can work if you want to use joined descriptors like, "Sexy and cute".
I hope that makes sense, I will include some better instructions in the next build for how to enter custom descriptors.
