ERRP notifications do not come from us, and you can ignore them.
ICANN has a policy for renewal schedules and notifications that doesn't make much sense, and is independent of registrars like us. This occasionally results in notifications arriving out of order.
As long as your domain remains set to auto-renew (which you can check in your dashboard), and you have up-to-date payment details in your account, your renewal will be processed on schedule. You will receive an emailed notification and receipt when the renewal billing has been processed.
If you have already received a renewal payment notification and receipt, and your domain remains set to auto-renew, you will not be billed again and your domain will be renewed on time. If you have any further questions, please let us know.
