SAPSCRIPT text printed only on second run

Hello experts,

I have the following strange issue when running tcode VF02 to see the printout from SAPSCRIPT.

When running for the 1st time the label is empty as you see in preview1.png even though in debugging I see it being populated in the OUT table.

Then when I press back, and print preview again the label is being printed as requested(preview2.png)
In both 1st and the 2nd run the value in the PERFORM REPORT is the samevalue.png
Any clue why it is being printed on the 2nd run and not on the first?

Thanks,

Chris
