Custom ring tones not showing up in iOS 7?

I apologize if this has already been posted; I searched the forum and couldn't find an answer. None of my custom ring tones (ring tones that I created and converted to .m4r) are showing up in iOS 7. It just starts with "Opening (Default)" and lists the default tones. The tones are checked to sync with iTunes and appear to be syncing (at least on that end), but nada on the phone. Has Apple blocked custom tones? I don't mind downloading some from iTunes, but I thought I'd ask before I waste the money... thank you!

 

Ok, I removed them from iTunes, re-added them, and then re-synced... that did the trick!
