Thank you. I think I already know what causes the problem (not yet clear how to resolve it though).
The report has a Summary band with five fields (one after the other horizontally). When the fields are empty Remove Line when Blank is checked. And in this case, all five fields are empty. But somehow the presence of the Summary band causes the second blank page. When I remove the Summary band, no problem.
So, I will need to figure how to make the Summary band disappear if all five fields are blank.
