ebup compile inserts blank pages

First, I did try to find an answer to my question in the lists.
My mss is in Scrivener, there are no blank pages. I compiled for .mobi and there are no blank pages. I compiled for epub and there are blank pages after some of the chapters. Am I missing something in the compile set up?
Thanks.

Is what you are describing any different than how some e-readers will display section breaks in the same fashion that we might deploy a page break, in a paper book? Some e-readers will stop printing text on a new chapter, forcing the reader to flip to the next page. Others will just display content in a tall stack, with no forced page flipping.
