Animation for character movement not being stopped on Task.WhenAll()

Currently have a await for my character movement (2 characters run into position once they reach their destination) the issue is the run (movement) animation doesn't stop even when I break out of one of the loops. It is waiting for both to finish the while loop, any ideas?:

 async Task MoveCharacter(Character character, int n)
 {
     character.SetMoveAnimation(true);
     while (Vector3.Distance(character.transform.position, character.PositionData[n].transform.position) > .01f)
     {
         character.transform.position = Vector3.MoveTowards(character.transform.position, character.PositionData[n].transform.position, Time.deltaTime * 3f);
         await Task.Yield();
     }
     //Shouldn't this be called on the character to stop it's animation when it reaches the destination? 
     character.SetMoveAnimation(false);

 }        

     List<Task> TaskList = new List<Task>();
     TaskList.Add(Move(characterA, n));
     TaskList.Add(Move(characterB, n));
     await Task.WhenAll(TaskList.ToArray());
