Try converting the ePub using Kindlegen and see what happens. If it works, load the resulting conversion into Calibre and using the KindleUnpack plugin, split the Mobi from the KF8 (AZW3). Then dump the Mobi and load the KF8. But if you need to make any changes to the KF8, the editor will allow you to make the changes before you load the KF8.
