Move it lower on your list and read the red text for hints at what weapon mods you have that are causing overlap. Any weapon effect mods? CE? Weapon rebalance mods? I have 540 mods and its almost always a load order issues unless you just werent paying attention and downloaded 2 mods that override the same thing. make sure the framework mod is placed high enough as well. 9/10 times a mod causes me problems, moving the mod as low as possible or as high as possible will resolve the issue. also put vfe core as high as possible as well as the weapon mods that seems to be causing you issues, so that other mods can make changes to them after. If that doesnt work leave vfe core up top and try putting the problematic vfe mods on the bottom. also highly recommend running rimpy, then using mod manager to fix any issues that are left.
