New plugin: Kindle Highlights

This plugin is awesome. One issue I noticed, and this isn’t a problem with the plugin, has to do with the export restrictions. I have notes from a book that show up as blank. I’m assuming this has to do with the export restrictions by Kindle. Any ideas of an easy way to work around this? If I delete highlights from the book itself, will it delete them in the file created or will the sync then pick up the new highlights?
