Mod Organizer improperly loading textures with both loose files and BSAs

[Doc4Holliday]

I'm quite new to using MO but understand modding quite well and have done it for some time. I understand that MO creates a virtual data folder and loads mods through that, however I found one mod which had a correct file structure, "Artifacts - The Ice Blade Of The Monarch" but after being installed with its scripted installer, the filestructure was right, but it's textures were misaligned on the weapon.

Extracting the BSA and loading the mod as all loose files solved the problem and caused the textures to appear correctly. Is there another way to correct this?
