TS 2020 - User Defined Reports - not displaying fields in report when printing to display, printer or pdf.

Hi All

I've written a User Defined Slip Summary report which uses a combination of slip data fields and some calculated fields. When I run the report to display, print or pdf, the first column and the final column print correctly, but then the calculated fields in all other columns do not print.

Interestingly, if I print the report to Excel, all fields print. I've inserted a snapshot of the report below; the first is from "print to display" and the 2nd "print to excel".

Print to display

Print to excel

Does anyone have any idea why the report is not printing as expected. I've tried it on a Windows 10 machine (latest updates) and Windows Server 2019.

Regards

Karen
