Bought Items have 0 Durability (Broken)

I have managed to set up Gui-Shop with prices imported from Item Price Calculator (https://umod.org/plugins/item-cost-calculator)
When buying something with Durability, it seems to always spawn with 0 Durability, aka broken.

Can someone replicate?

Nevermind.
When simply importing the Pricelist from Itemcost Calculator, it is NOT generating enough Metadata, so the gui-shop fills them in blank.
that way, the items start with 0 durability.

if that happens simply run the chat command /resetconditions  in game with the guishop.admin perm

Sounds like Itemcost Calculator requires updating
