Missing sights on GLs

Hello everyone,
I currently have this issure with my grenade launchers:
The sights on both of them are missing but I can still switch between them in-game, shifting the view when ADSing.
Does anyone know why this may be? I have tried disabling all my mods and veryfing game files (which found nothing).

I found the culprit.

It was the Akimbo Ironsights Mod. It has these files in it that somehow mess with the sight.
