Mod content not auto loading when trying to join a server

I have looked for solutions and kinda found them. My PwS refuses to autoload the mods when I attempt to join a server. I literally have to put in the start up params to get them to load. They are there in the default folder and everything. They have also been downloaded through PwS. Occasionally when I attempt to join a server and it kicks me for whatever reason I'll have one or two of the mods autoloaded. For instance I just tried to join The Wrecking Crew ACE+ACRE public server at and the only things autoloaded were ARMA 2, Beta, Expansion,@CBA,@CBA_A2.I am running CO through steam.
