Topic: Built Decks Column Not Working

Having a slight problem with converting one of my WIPs to a built deck. I have some cards that I only have one of in my inventory, and only one deck where it's used, but it still shows up with a 0 in the built decks column. It's even weirder because it shows up (correctly) as in a built deck in my inventory. How can I fix this?
