On 3 of my melee toons (ret pally, frost DK and fury warrior) it’s telling me that I need to do a bonus roll for Seeping Scourgewing when all 3 toons already have it and it shows in Best In Bags after importing their gear. And the one it’s telling me to bonus roll for is identical to the one I’m wearing (ilvl, no sockets, etc.)
Could you post your addon export (the string you copy from the addon to the website) for one of your characters? Then we can try to reproduce what you are seeing.
