Stuck after slappy finer grind mission

I’ve completed the slappy finer grind mission, however now it’s saying I still need to complete it and I can’t progress now in the game because all other missions are locked until the finer grind one is completed even though I’ve already done that mission, there’s no icon on the map to re do it or anything, so now I’m just stuck at this point, ea please fix this I been waiting for years for this game and now I can’t even progress on it
