First-Person Arms Stretched while using MW2019 Weapons WEP

[fleet trench]

I tried restarting the game, reinstalling the mods, and changing my player model to no avail. If it helps, I'm primarily using these mods in the screenshot:

Found out what's happening but still, no solution, unfortunately.
Apparently, my arms stretch while using the mod.
