Help with Graphic Novels and book illustrations

[TheSmitty]

I have several graphic novels and some books with illustrations that I used Calibre to move from my kindle onto my Kobo Libra. They move and open just fine but the in the case of the comics the panes are smaller than the screen display and not centered. The same happens with novels that have illustrations, the illustrations are there but they are smaller and not centered like they are on the kindle.

I converted them to epubs to send to the Kobo. Is there a different format I should be using or some setting?

Thanks in advance to anyone who offers up ideas
