The quest "Fel Reavers, No Thanks!" doesn't work as intended. Did some looking around and found a fix (partial) to this quest thanks to Trinitycore.
Only problem is, is the quest can't be turned in on completion. I believe the way it's supposed to work is it's triggered through some spell or quest I think. Take a look at it here: https://github.com/TrinityCore/TrinityCore/issues/16269
You can remove the SpecialFlags value but doing so would be a hack fix I believe, not sure.
