CD music not available on iPod

I'm working from a new Windows 11 computer with the latest version of iTunes and an iPod touch. Upon syncing my music collection, I find that the iPod will not recognize music I burned from CDs, stating "This song is not currently available in your country or region."

My region is set to my country. I've tried to play these songs on iTunes itself, and they'll play there without any issues.

I do not have an Apple Music subscription, nor do I want one.
