Tooltip and right-clicking to swap between equipment set doesn't work after one of the equipment set profile was deleted.

If a new equipment set is created, the addon works properly again. But when this new set is deleted, the problem comes back.

So I fixed this issue by just deleting another equipment set. What happened is there are 2 identical equipment sets, one was equipped, and another one was deleted. I think this maybe the source of the issue because now that there is no duplicate set, deleting an equipment set doesn't cause the problem.
