Preview this record' icon for the RITM it shows both populated and empty variables on the RITM

[GChanner]

When I am on the sc_task record and click the 'preview this record' icon for the RITM it shows both populated and empty variables on the RITM (see attached images).

How can I hide empty variables from the 'Preview this record'?

Image 1 is of the RITM and image 2 is when I click 'preview this record'.

According to KB0656244 , Client Scripts and UI Policies are not supported in the popup/reference icon view so I don't think you have much of a choice.

That aside, I did find a couple other bits of information you might find useful.
