[2022] Accepted a duel.... won... didn't count for Isobel's Favor

for the Isobel's favor achievement you have to accept a duel.
I normally have auto decline on because I hate dueling.
now how many duels do I have to go through before it'll actually trigger the achievement? because apparently 1 was not enough.
Cause I'd really like to go back to ignoring duel requests, they're obnoxious.
