Bug Party Essentials Kit objects not functioning

Hi, 

I've recently bought the Party Essentials Kit on the marketplace, however many of its objects don't work. the only thing I can do is to put them as a family object. The kit is active on the marketplace, I've tired to uninstall it and re install it, try in a new save but nothing works. 

I don't have any mods or CC. 

I'm coming here as we couldn't find a solution on the French forum and I also saw someone else have the same issue with another kit and on PC. 

Thanks!
