A OnePass by design will record shows that do not have an OAD (Original Air Date) to be safe since that's what is used to determine whether as show is new. Typically these shows have generic guide information as well and it sounds like that's what you are running in to. A new OnePass will also record any show that has an OAD within I think it's 30 days of when it's first set up as well to be sure you catch episodes that you might have missed.
