Certain entities no longer show up in spawn menu

Certain addon entities (like WAC, Siminovs weapons, SCars) don’t show up in the spawn menu (Not listed) for some reason.
Some of my entitie addons will show but meh. Even recently I installed a new addon that included both weapons AND entities to test this issue, and while the weapons were there, the entities were not. I tried disabling some addons and SOME entities showed up again, but not all. I kept disabling more but I’m still having the problem. All the addons used to work fine together. Please help
