This means that if the book creator hard-codes some settings, they cannot be overridden. Or results in worse looking books. The kepub renderer will override different things, and generally, I find doing this results in a worse result.
Of course errors in the original epub will cause problems. What and when depends on exactly what you are doing. But, the first thing to do is to check the book is actually on the device. If something went wrong and it didn't actually put the book on the device, then the device can't read it. Did the conversion work and produce a kepub in the library? Were there any errors from the driver when you sent the kepub to the device?
If you are actually using the KoboTouchExtended driver to transform the epub to kepub during the send-to-device, rather than doing a conversions, there are options in the driver for what to do if there are errors in the book. This can be to fail quietly and not send the book.

my experience has been horribly the opposite. while everything generally works great i haven't had a single epub work eith extra typography settings. i procure books from gutenberg, feedbooks, and many other well known sites and even some sitez that specifically focus on clean proper ebook formatting.
if i use the stock fonts everything is fine. if i use sideloaded fonts i haven't seen even one epub work properly. for instance, if i load alegreya font on an epub it is bold. always. convert to kepub and it works as expected. if i use bitter font and adjust line hight, the line height jumps 10 times the normal amount at each setting step. and the margins similarly act all wonky.
bookmarks have issues as well and sometimes dissapear and act funny. with kepub I've never had an issue. and in every case converting to kepub has been the best solution. and thus my problem. harry potter converts fine, but my kobo doesn't find it or even acknowledge it exists. and i can't seem to figure out why.
