Sweetwater Transpose question

I think it will be erased, since everything from the Empress item is carried over to the Sweetwater equip.

When I transposed my Empress DBG to my Sweetwater DBG, the Nebulite carried over from the Empress DBG.

I know that if the emrpess glove had a nebulite it would overwrite the nebulite on the sw glove, but in this case the empress glove would have no nebulite to carry over. i want to know if since the empress glove has no nebulite and the sw glove does have a nebulite will the nebulite on the sw glove remain after trasnpose or will it be erased since the empress glove didn't have a nebulite.
