Multiple Realms

Okay, somehow I now posses two realms. One called Ancient Isles, while the other is called The Ancient Isles. I think this had something to do with me renewing my subscription. I renewed my subscription, and my old realm, Ancient Isles renewed, but I also had the option to create a new one, the Ancient Isles. On a friend screen, there are actually three, another called ancient isles. I have no clue how this came to be. I would like Ancient Isles removed, and would like to keep The Ancient Isles, but I'm not sure how to change this. I placed this as private, because I suspect this could be seen as an exploit. My minecraft username is Minebomb50. Any additional info that is needed will be provided when it is asked for.
