Books imported via Obok do not get the .kepub.epub extension (unless you are running a modified version). Since the original book does not have any file extension, when the filename is created, the extension is simply .epub. kepubify will not convert them since they are already kepub. I have never checked to see what KTE or calibre 8+ will do with them. Hopefully, just a rename to .kepub.epub while sending.

An kepub is simply an ePub with a mass of added spans and some simple JavaScript. On a Kobo ereader or app, those are made use of. On any other platform, they are treated as null operations and disregarded. If you happen to run Modify ePub, with the Strip Kobo DRM remnants, Strip spans and Remove inline javascript and files, it does a decent job of de-kepubifying the files.
