I think it's a feature, not a bug. Basic Web is the only thing that is available until you add MP3s
Once you load some MP3s, it appears that Play MP3s will be available as a choice.
Text to Speech is available from within a book, not from the Experimental menu, so while the feature is described there, you will not be able to access it from there.
