problems with downloading mods and problem with folders

I've had BeamngDrive for a while now and had no problems with mods, until now. When wanting to download/install a mod, the green auto install button is missing. So I try to manually install the mod(once its done downloading). I normaly don't have troubles with this. When I open the mods folder and the downloads folder I cut and paste it in the mods folder. I then open my game and it doesn't recognize the mod. I then saw a vehicles uncompressed folder inside the mods folder. I put the vehicle mod in the folder and the game recognized the mod and it showed as 1 more mod in the game. I also downlowded a map mod and put it in the vehicle folder(inside the mods folder), and it worked. It showed up as unrecognized(the icon that specifies if the mod is a map or vehicle was a ?). I unpacked it and I really know what that does. if anybody knows why the green button is missing or anything about the files please answer. Thank you.

 

1: some mods don't support the auto install feature
2: where exactly do you put your mods?
It's usually your documents > beamng > mods
3: also you just cut the zip file it is enough
