Members not showing up in my subscription

I have a wordpress site and have membership pro integrated with CCBill as my gateway. I'm getting email notifications that people are signing up for a 3-month memberships but when I sign into the admin, to look at my members, they are not showing up in my membership log.

I don't know if I have the plugin configured properly or not. Any help or ideas you can send my way to fix this?

Thanks for your time
