Nothing was wrong with your domain renewals, all you had to do was click the link in the email to get an answer as to why you were getting transfer requests:
"We have a new renewal process in place as of 2/1. Previously RegisterFly.com used multiple providers to handle our backend domain name registrations. We are now consolidating from multiple providers into RegisterFly.com directly. When you submit a renewal request we will be requesting the transfer from the different providers directly to RegisterFly.com, inc an ICANN acredited registrar. When the name transfers over (usually in a day or so) the full year will be added to your domain name. Your site and settings will remain unchanged during this transition. If you have any questions please feel free to contact our support department at
[email protected]"
Also, Registerfly is just a reseller for Enom. No need to freak out, as the info said, the year added will be reflected in your registerfly account once the transfer has been concluded.
