NaNM repair glitch

I am unable to repair any of my gear at a blacksmith, armorsmith or swordsmith. In the top right it says the amount i am supposed to pay is NaNM. I’ve tried to put all my gear in to a chest and sleep or save but this doesn’t seem to work for me. Does somebody have a different repair or a way around because i have some gear that can’t be rapired with kits anymore. Any help would be much appreciated. (PS4)

For anyone still experiencing this problem, i don’t know if it is related but after i did the Vranik quest the glitch dissappeared and i was able to repair anything again.
