For some reason I can't find/separate the "Unaired Network Promo".

And, without logs, it is impossible to say how, except... What is your minimum title length in Preferences->Video?

Default is 120 seconds. Promos are usually 30-90 seconds. Anything shorter than your minimum won't be selected, or even available for selection (log will show that the too-short title was skipped).

I am a horse's ass. That was the correct solution, I can't believe I missed it. Thank you very much.
