A blog subscriber that is receiving duplicate email notices while others are not?

I have a unique problem right now where a user has told me she is receiving three emails each time we sent one. And, this is not the problem I had previously. The problem I had previously was because I had two copies of my site on test servers and the cronjobs were running on the real site and the two test sites so we were sending out three emails to everybody, every time.

Now, I only have heard from one of our blog subscribers that she is receiving duplicates. I have queried the mail server which is a gmail account and sure enough this user is receiving duplicates. I have searched for some other users and they are not.

I searched through the EasyBlog Subscribers list and found that this subscriber is only subscribed once and is subscribed to the "Entire Site". This is not an EasySocial user but is just somebody who is subscribing to blogs.

Something else I noticed is that most of my subscribers are subscribed three times to the Entire Site. I am assuming this is not right and that I should be deleting two of the subscriptions for each of these users. I am not sure how they are subscribed three times but wonder if maybe this was caused when we had the test sites that were sending out emails?

Any insights you have into this will be appreciated.
