[2.1] Wrong target for duel of honor after melee

After a melee, my character was accused of cheating by a rival (event 100422). I could either choose "I won every match fair and square!" which dismisses the event chain, or, choose "Your 'evidence' is dishonoring, I challenge you to a duel!" (tooltip: "is challenged to a duel") which results in a duel. But the duel is actually against my playing character instead of against my rival.
Just after accepting the duel, the next event pop up (event 100427) is reading: "[Playing character]'s face turned red and he started sputtering swear words when I accused him of cheating in the tournament. I had made sure I made the accusation where as many people as possible could hear it, something I came to regret quickly when [Playing character] challenged me to a duel!" with 2 options: (1) "I accept, but don't you cheat this time!" and (2) "I jest, I jest! Please don't hit me..." (tooltip: "Lose 25.00 Prestige[new line][Playing character]: have never seen a more spineless creature than [Playing character]").
And if you select option (1) the duel against yourself ensues.

N/A

Thanks for your time and consideration
