When I print reports, it shows generating page 1,2,3, then it goes through page 1,2,3 for the second time. Why is it going through these pages twice?

RTPro prints 'Page 1 of 3' on the top right of each page on the reports. The first time through, program finds the total number of the pages on the report, in this case 3, then the second time through it generates the actual report.
