Missions in Red Dead Online

In my opinion, it would be a nice feature because I won't have to replay the game just for the mission.

So my game is bugged and I can't complete this mission in Red Dead Online. Like, I can do the mission, but it pops right up on the map again. I've done the mission three times and its still there.

Anyone else have this happen to them? And anyone know how I might fix this so I can get on with the quest line?

Is there an infinite number of Bounty Hunting Missions or can you stop receiving them?
