Halt and Catch Fire recorded last might episode three times

I have a season pass for Halt and Catch Fire, set up for new shows only. Last nights episode recorded three times, at 10 PM, 11 PM and 2 AM this morning. WTF! I thought Tivo wouldn't record a second showing if you have it on your DVR, or recorded it within the last 28 days. Any ideas why this happened.
