Is there any debugging that can show how an item has been scheduled from Station Rules -> Show Rules -> etc

I'm not sure what is happening in one of my clocks, I've had to force a style within a clock as it's not being picked up by the show rules, even though they are correct.

I'll take another look today but can't seem to work out where I'm going wrong.  I've not had many issues with Scheduling so I'm not sure if I've come across a bug?


Things I have checked:-

Song Categorys and Styles
Show Rule for that Clock
Style rules for the song
Station Rules


So please could someone shed some light on this?   This is hard to describe.  I think I'm after the process of how the scheduling works so that I can fault find and test.
