[RESOLVED] Report Header and Footer disappear when Exporting

When I export my report to a PDF, everything is fine. However, if I select a group to drill down and then export that drilled down report to a pdf, the reports header and footer disappear. How can I fix this? My report has a few subreports, so that might have something to do with it.
Thanks

This is marked resolved. Is it?

If so, what did you do to resolve it?

Go to file > Report Options and tick "show header and footers on drill down"
