There are a lot of mods that use a "customization_items" file, and there can be only one of that file in an install as far as I know. I would say it is a mod conflict (especially if you are using any clothing mods as well as an uncensor since both use their own " customization_items" file and one will cancel out the other.
If I use an uncensor and this mod, installing the uncensor last makes this mod not work properly (problems similar to what you're describing) If I install this mod last, this mod works, but the uncensor doesn't.
