Nexus mods i installed manually aren't enabled

[TheGreatCornhulio]

I added like 10 new mods to Skyrim SE and when i loaded my game all of the mods i added aren't there in game(except my reshade and enb), i can open the mods tab in the menu and i can see all the mods but it won't let me enable or do anything with them. i could use some help on figuring out how to havee them enabled>
