I have the same issue.  The problem is that I do not know that I have a problem until the client tells me they never received the "Link" information I sent to them.  The email address is the same, so that is not the problem.  So I inactivate one of the accounts when I discover the problem.  I would like to delete the inactive account but I do not see a way to do that.

I will monitor this thread to see is a solution to our problem is available.
