Presidency calling advice

A friend of mine who's in a presidency calling has a counselor who feels they've been wronged to the point that they're telling other ward members about it. From my perspective my friend has done nothing intentionally wrong and has gone out of their way to make things right but nothing seems to help. As the president what can they do? It's starting to feel like they need to tell the Bishop and potentially have this counselor released. Seems like that amount of contention can't exist within a presidency. Any advice?
