Adobe Digital Editions - page numbers in mobile versus desktop

I notice when I use ADE on a desktop, ADE will show two sets of page numbers - one being the page number corresponding with the print book and one that is more of a page count.  However, when I use ADE on a mobile device, the page number corresponding with the print book is missing.  Why is that?  And is there a way to request that Adobe include this feature on mobile/tablet versions of the app?
