Double Line Formatting

Hello,

We currently print out a book to our general managers every quarter and our reports formatting seemingly changed without us changing. We use double underlines as our totals and previously it worked fine, but this quarter it looks like a solid line, but when you zoom in, you can see it's a double line. Is there any way I can fix this? I've tried changing the ReportBottomLine1Thickness and ReportBottomLine2Thickness size, but with no luck. Any suggestions?

Thanks,

Will
