Crystal report Drill down tab won't print(WPF)

Question

The issue is when I open a drill down report in runtime I will see the view I want but when I select print it only prints the main page every time.
I have found that exporting to a PDF works. we need the runtime in our software application to allow the drill down level to print not the main report page

Any help would be greatly appreciated, thanks

version of the SDK : 13.0.15.1840
