Pictures are placed in the wrong order. (bug on the forum engine).
Where on the computer are you trying to import the files from? If they are on an external or network drive please copy them to your desktop, for example, and try again.
If this does not work are you able to attach one of the MP3 files here for us to take a look? If you would prefer not to post them onto the public forum, please open a support ticket.

Thanks for saving those MP3's.
I did not have any issues adding those MP3 files to a scribe.
I added one to soundtrack and one to Voice over with no issues.
They seemed to be names differently that the ones in your screenshots.
Perhaps it may have something to do with the file names, try renaming the MP3 files maybe to sparkol.mp3 and retrying?
I have attached the example scribe here.
If you have further issues, I would suggest creating a support ticket
