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).

Disabling all mod_overrides too?
Including custom beardlib mod and normal replacer mod?
