Gmod Addons Wont Load

When i go into gmod it installs the addons i want and i see them in the list activated when i reboot my game they arnt there but i checked my gmod addons folder the addons are in the folder and when i reinstall them in gmod it seems like gmod just rescans the folder for the addons and then adds them to the list also when i load a map without reinstalling the addons they arnt there so i dont know how to fix this
