I have a report with one header and two fields in the details section. I have formatted the details section to have multiple columns, down then across. That's all working fine. I have also added a line down the right side of the report, through all sections, and then a line in the page footer, connecting with the right side line. It looks fine and prints fine, but why is there a line hanging out in the gray frame, mirroring the right hand line?

If I use a box around the whole report, it creates multiple boxes around the details section fields/data, which I assume is because of the multiple columns formatting. Long story short, is there something about presenting data in these columns that messes with any additional formatting?
