Back continue unequip alone

[Wolfyx]

Hallooo! From this mod World Wide Mercenary Gear Pack at Fallout 4 Nexus - Mods and community (nexusmods.com) the backpack (all of the them) keep getting randomly unequip. I've tried several time change the slot with fo4edit but the problem is that when i change i can equip but no model shows up in game.

 

If unequip i cannot equip but "alway randomly" i can equip it. They use the sloth 58 unnamed but as far as i know i've no other item that conflict with that slot.
