Premier Not Recording Shows -- Claims Duplicate

The past few days I've noticed that my Premier wasn't picking up several upcoming PBS shows--looking in the TDL it says they're not going to record because they're duplicates, but they're not. Then today I noticed that it wasn't recording Red Bull Signature Series--and it wasn't in the TDL at all from any view, nor in History. Going to the One Pass it listed the currently airing show as upcoming, and though I noted the guide info said the show first aired last August when it's actually new, I have the OP set for new and repeats. Just for fun I tried deleting the OP and creating a new one, and now the program appears in History as not recording because it is a duplicate.

The PBS shows not recording due to being duplicates also happen to be repeats, when the OP is set to record new and repeats. It's almost like something thinks repeats are duplicates.
