Missing mods / script mods

I downloaded a bunch of mods and script mods to build a house with, put them in the correct folder in my files and went into the game turned on custom content and mods and of course script mods, left the game so it can update that to be in the game. I then went back into the game, it told me that the mods and script mods are all in my game and enabled but when I go to build, they are not there and I can't find them anywhere. I have no idea what to do or how to find them, I searched the game up and down and have no idea what to do because I just want to build a house with my cc but it's not showing in my game, and I am really confused. Someone please help me figure this out.
