Friend, I solved the problem! You need to remove the hands mesh from the nif file altogether.
Go into CK.
Open ArmorAddon of your armor.
If your outfit is a complete set of armor in one file, select: BODY, Forearms, Feet, Calves.
(Do not choose hands, then you will see why.)
Open your Armor
Choose BODY, Hands, Forearms, Feet, Calves
SECOND: in the lower window where you add AA to your armor click rmb on the blank field and select "new" and add "NakedHands" and "NakedHands" for all races.
Save and check in game.

PROFIT!!!
