Recordings showing that I never set

Bear with me please, just got a Tablo. Formatted one of my existing usb hard drives. Actually working well over roku, will be testing the new app tonight. No stuttering or any problems except one. When I navigate to Recordings in my web browser, it shows tons of shows I have never set to record. Some say they were recorded, some say “Failed to record…no hard drive” and such. I have been deleting them one by one, but have no idea how they get there.
