fixed layout epubs from InDesign in Adobe Digital Editions look terrible...what is going on?

I am preparing a fixed layout v3.0 epub from an INDesign CC 2014 document.  The book is 178 pages with embedded imges throughout.  The resulting epub when opened in Digital Editions looks ghastly...enormous overlapping type; epub said to have 758 pages when the original has 178 pages.  The same file opened in iBooks looks beautiful.

What's wrong with Digital Editions?

Anyone having the same problem?  Is there a fix?
