What the hell is wrong with Appearance Mod Menu?

Things immediately come back even after despawning them, and the arcade machine keeps defaulting to the roach race arcade when I'm trying to just get trauma drama. I'll spawn it in as trauma drama, save it, then save the preset, then when I reload the preset, it's fucking roach race again. Am I doing something wrong or is this mod just broken code cobbled together with string and scotch tape?
