For example, on Demon Hunter, it says I'm missing the Great Ray's Longbow from the rare Bloodstripe Great Ray, even though I can't equip bows. Settings filters aren't set to be seeing this, and I don't see unequippable stuff in any other zone.

requesting api update (.e.g bow is only for hunter/rogue/war useable) takes a bit.
we should have it fixed in the next version, if not a little bit later
