Hmm. I noticed something similar after the patch. My gear level was stuck/not updating. What worked for me was deleting the gear set and setting it as a new set. I'm not sure how exactly what happened, but the default setting now shows the iLv of the gear set instead of the weapon level like it used to show. You don't have to unequip anything, just delete the gear set and create a new one, see if that works.
