Weird problem - some 8:00 AM shows showing up as 7:00 AM shows when starting a playlist

Here’s one I’ve never seen before. If you open up a new playlist for any of our 4 Saturday 8:00 AM shows (Rise Up, Robin’s Radio, Melody Divas, Transmutation), the New Playlist Form shows a 7:00 AM start time (we have 4 such shows because they’re each biweekly). I also noticed this for our Monday 8:00 AM show (Get Up). I’m not seeing this problem for other shows/other timeslots.

Any idea what could be causing this? They clearly are still listed on our schedule as 8:00 AM shows!
