iPhone 5 - Custom Text Tone not playing

[sparkstsa]

I have being using a custom ringtone for text messages ever since I got my 4s last year. For some reason, my new iPhone 5 refuses to play the tone when I get a text. I can select one of the stock tones and it works fine. This shouldn't be iOS 6 related because it worked fine on my 4s after I updated.

Anyone else having similar problems?

Yes, I have the same problem.

Also, I notice that some of my custom ringtones show up as alert tones, and some of them show up as ringtones. That never happened before, and I can find no information anywhere as to what the difference is. It's not the length of the tone. There's no difference in iTunes between them.
