My mods and script mods will not stay enabled. After I add mods into the folder.

I firstly removed everything from my mods folder and then I enabled the mods and script mods. Exited the game reopened it and they stayed enabled. And then I added refreshed main menu by simmatically. To start smapp either adding 1 mod. Opened the game and then mods disabled themselves. So I enabled them exited the game and then reopened it with the mod still in the mods folder. And they disabled again my mods folder will not stay enabled unless it is empty.
