SBEP Models won't spawn

Hi. I need help as on my server the SBEP models won’t spawn. Through the Props tab or the Browse tab. I have the SBEP folders in my addons folder serverside. SBEP_Entities, SBEP_Models etc…

Can anybody help me? I need this ASAP as otherwise the Spacebuild server will be useless.

Do you also have them Clientside?

Yes. They show up in Single player and in Multiplayer.
Don’t you think I’d check that? ~_~
