I had the same problem, what I did is I deleted my PSA Commercial playout policy and then I unscheduled and reschedule the playout log and everything like the IDs and the PSA Commercials show up with the songs.
currently having that same issue, never had this happen before... I'll try doing what you did, however only playout policy in place is for music.
Even though I am scheduling PSA and station IDs in the clocks, only the songs appear in the playout log and in the playlist. I watched the tutorial and did everything correctly but my hours are coming up short in the playlist because nothing but the songs are being chosen. Am I missing something?
