Please submit a bug (see the first post for details) and be sure to include the calibre debug log from sending one of these books to the Aura, and attach to the bug both the original ePub from the calibre library and the generated KePub file from the device (or the copy from using the plugin option to copy generated KePub files). Specific directions are in the first post of this thread and when creating your bug report.
Unfortunately, a lot of bugs involving KePub files on the Aura are specific to the Aura and I don't have one to test with, so you may need to do a bit of testing back and forth with me.
