Pennsylvania EUP Pack Not Working

Hello I tried to install this eup pack https://www.lcpdfr.com/downloads/gta5mods/character/14805-pennsylvania-state-trooper-eup-81/ but it just won’t work! I really need someone to help with this I have no idea why it wont work. Only 1 of the shirts work, and 2 hats work. The rest like the vest, pants, and everything else just doent show up. Yes I have the Patreon, yes I have a key put into zap. Im stuck and my server really needs this pack.
