Looking at your song edit .jpg. It would have shown more if you had highlighted the song then all the bottom boxes would have shown whether you had any 3 tick boxes at the bottom selected, I notice in the genre column it looks like you have it set to "Acappella". I'm wondering if this is a clue.
If you now look at your MTU.jpg. I notice you have the box ticked for Use Exclude checked items. Now in the right hand payne click on the + sign of the genre this will expand the list, have you got the acappella box ticked ? if you have that will prevent any songs with that genre appearing, while you have that list expanded check you don't have any others ticked that you want to appear in the songbook. Alternately untick the "Exclude checked items" so that it does not exclude anything.
One other point, in that box I see you set the date range from the 13th to 18th and todays date is the 19th so it would not print anything that was entered today.
See if the excluded folders is the problem if not report back.
