Friend Requests Bigged

whenever someone sends me a friend request it takes a while for it to show up, then when i accept it, it does not go away from the request tab. if i try to click on it and add them still it says "Error, Failed to accept friend request. please try again or accept from your platforms friend management". i have found if i restarted the game it disappears from the request tab, but i dont wanna restarted the whole game every time i add someone.
