Conflicting custom objects

Hi I am super new to creating mods but l have been working on adding custom interactions to some deco sims I made. I made the interactions for two object deco sims and they both work perfectly fine when one of them are in my game but when I add both files into my mods folder only one shows up in game. I am assuming this means there is some overlap somewhere but I am not sure where to look or how to fix this.

I will provide google drive links to both package files for the objects below. Any help is greatly appreciated
