[SOLVED - problem between chair and ebook reader

- see below]
Quick question (couldn't find an answer when searching here): I installed the Touch Extended, KePub Metadata reader & writer drivers and disabled the "standard" KoboTouch driver in Calibre 2.31.0, and restarted as per the instructions.
When I plug in the Kobo Glo HD and select Device > Configure This Device, KEPUB does appear ticked at the top of the list (and the options panel is definitely the one from Touch Extended, not from the standard driver).
The problem is
when I send books from the library, KEPUB doesn't appear when sending specific format.
Solution: The list is of SOURCE formats in the library, not targets DUH! When I send the EPUB it does get to the Glo as .kepub.epub.
Sorry about that!
