The majority of these books were originally .lrf. .lit or B&N epubs. Converting these books to mobi and then back to epub seems to 'fix' them so they can be read on the Kobo(s).
Common complaint about Kobo actually using the embedded styles while other ereaders seem to disregard the embedded style and use a generic stylesheet. The only time I've had that issue on legitimate epubs (not from the result of converting other formats to epub), the issue was traceable to styles that the Kobo was trying to display as intended.

Same book works perfectly on my T3.
The only times I've seen that on my collection of Kobo ereaders is when I manually deleted the ebook from my computer's file explorer and then replaced it with a new copy. Using either Calibre or the Kobo GUI to delete a book has not caused the problem -- so far. My opinion is this issue is due to the database not being cleaned up so the new copy is using the old book's information.

Try deleting the book using either Calibre or the Kobo GUI and then reloading it to see if it now works.

I've compared a couple of other ereaders including a Sony and an Ectaco to Kobos. What I can say is that Kobo displayed the ebook's styling including wide margins and line spacing correctly even when that correctness was a pain to try to read. On one ebook, the margins on the Kobo were ~2cm wide and the lines were double spaced with ~1cm gaps between paragraphs. Looking at the stylesheets (6 of them plus an Adobe page-template.xpgt!) in the epub after removing the DRM, that was exactly what the publisher (Bloombury) intended. Trying to read a page using the same screen real estate as the book cover uses when sleeping in non-fullscreen mode is not "A GOOD IDEA" in my not so humble opinion.

I won't get started on stylesheet that use points (talk about relics from dead tree books) or pixels for absolute sizing rather than % or em to allow scaling.
