I'm sorry if I didn't make it clear, but I meant choose "Render text as images" on in5 export, which should maintain the layout (not put in the extra spacing, etc.). If you want to send over the InDesign package, we can take a look at what's going on with it. Send us an email with a link (dropbox or wetransfer or similar) to the InDesign file: support@ajarproductions.
