Report Transformation Script Option Test not working

I have seen many entries regarding using Script Option on Report Transformations but I cannot access the box to add any script. Did I miss anything on how to use the Script option?

Manager edition : Desktop
Software version: 22.8.8
Your operating system and version: Windows 10

Screen shots of any error messages

I can confirm this on cloud edition.

Fixed in the latest version (22.8.10)

Thanks lubos.

I confirm, it is working.
