Item equipping itself when trying to switch it in an outfit

Hello!  I use Outfitter in Classic WOTLK and love it!  I have one problem currently.  I have a pair of gloves that dont want to unequip.  As soon as i swap them in Outfitter, they immediately swap back.  The only way i have found not to swap to them is putting the particular pair of gloves in the bank, but i need them for my other spec.  Is this a bug or am i missing something?

Thanks!!
