Note by [Mojang] Mega_Spud (Jay Wells):

If you participate in the beta, you can upload your world so the developers can look into the conversion issues such as this. (Please mention the receipt number in this report or take a screenshot of the receipt and add it to the ticket!)

Instructions:
Highlight the pre-conversion world you have issues with. Press Y. Follow the dialog and upload the world. Once the upload has finished you will see a receipt. Supply the receipt on this ticket as a image/screenshot/photo (clearly readable) or text.
