I can swap items out of the bag in Bank Slot 7 and then they are counted as normal.

Looks like they added another bag slot and it's not counted as part of their constants. Why am I not surprised. I'll see about adding it.

I'll have to check. Please let me know what are you using. Classic, WOTLK, or Retail. In the past I didn't have to ask that but these days it's important.
