Missing files error when enabling some mods

[koozildo]

So, when I try to enable some mods, there's a massage about missing the files: Dawnguard.esm, Dragonborn.esm and HearthFires.esm

But I already own the DLC's and installed it. The files are in the main directory.

 

It seems I'm not allowed to use images on the post, so, here'is the link to it: https://i.ibb.co/PN2ZHFH/skyrim-1.png
