ESP Missing from Nexus Manager & AddItemMenu?

[LesboIsBesto]

So I added this armor mod to NMM and it didnt install anything except the esp file so I had to reinstall it manually & built the outfit in BodySlide. Then when I launched the game, AddItemMenu could not find the esp even tho NMM said it was activated. So I replaced the esp manually & activated the new one & it appears in AddItemMenu but scrolling thru any item in it crashes my game. Also reinstalling the mod entirely manual from the start results in the mod's esp not being listed in NMM at all. The esp is present in my game files however.

 

This is the mod itself: https://www.nexusmods.com/skyrim/mods/105187?tab=description
