I had this problem too, it doesn't let you save it or return to same page. What I would recommend is complete a form by hand. Then using the pdf input the details one page at a time. Print that page and then move onto next page.
In the end you will have a complete handwritten form E and a corresponding typed up form e.
Then just photocopy the final typed up version and send to court and exchange with otherside, don't forget to get one for yourself.
