PDF export issues (1 Viewer)

I am trying to export my form which has many different pages and filters for each page. It is exporting properly, all the different forms are there but when when I open it , there are blank pages in between each one and a grey rectangle appears and pushes the following form down screwing up the format then continually messing up the rest of the next forms layout.

Any advice would help!

Most of us would export a report. You have little control over printing forms, and essentially what you're doing.
