What you were expecting to happen, and what actually happened?
I had won 6 games in a row in the arena. I saw my guild was flashing so I relogged. When I came back the game said I had 2 losses.
What are the steps to make it happen again?
I am not sure. There were a lot of retry error messages going on beforehand while I was doing the arena; that may have something to do with it. This was on the PS4 version of the game.
