Can't find all Quixel Modular Building Kits on Fab

Hello

I was trying to navigate Fab to find all the parts of a megascans building (the series they produced like Neoclassical Modular Building 1, 2... etc) but it seems that some of the kits just aren't on fab? Neoclassical Modular Building 4 I've gotten most of the floors but can't find the kit for the 1st floors... Other buildings I can find even less...

Has anyone else had this issue?

Cheers
