Someone at CO needs to fix this "double orange" problem, ASAP. Same thing happened to me on my flight just yesterday (TPA/EWR), and it caused an issue on the flight -- 2 people had the same exit row seat assignment. I pushed the call button several times to resolve, with no F.A. repsonse at all (bad). My "seat sharer" noticed the gate agent on board, so I called out the issue to him. He had no interest the issue, and just yelled back to take another seat. Fine. But he didn't even ask if it was exit row, which would have mattered if there were no others. Luckily, there was another, and it was not a big deal, but it could have been for all he knew or cared. And isn't that his main job function at that time to resolve seat issues?

Anyway, I just want to add my experience to the thread in case that someone at CO is reading it. Hope this helps.
