Just curious if anyone has any insight into what happened here:

I made a reservation in an exit-row seat. Later, I realized that I needed to bring my dog along in-cabin, so I moved myself to a regular seat. Later on, I called in to make the in-cabin pet reservation. The agent told me I would need to change my seat, as I was in an exit row. I'm not, I said; look at the seat map. He agreed and eventually was able to make the reservation.

At every single step along the way when I interacted with an agent I was told there was a problem, as I couldn't have a dog in an exit row. At each step, I patiently pointed out that I was not, in fact, in an exit row, and had to spend another five to ten minutes waiting for the agent to figure out a way to override the problem. At one point, when I tried to change myself into yet another non-exit row via the app (flight was massively delayed and some passengers dropped off), the app denied the change, saying that the new seat was an exit row and thus not permitted with in-cabin pet. I was in the SC at the time, so I went up and asked an agent. He couldn't make the change for me as the flight was under gate control, but he did confirm that the seat I'd wanted to change to was NOT an exit row.

So...what was the deal here? Why was there some sort of exit row flag on my reservation that wasn't cleared even though I'd made the in-cabin pet reservation AFTER changing to a non-exit row seat? Is this a known bug? Not a huge deal, but I'm curious.
