Just completed the daily PvP player kills, did not get my potion of PvP Reward from it though. Everything else seems to be fine. Though it did not automatically remove it from tracked achievements either, so maybe that has something to do with this.
Edit: got it (the achievement) in Stronghold match, that we won (not so sure about that as winning should have also triggered thief winner, but I think we won), and no I wasn’t playing a revenant.
