Information panel from data probe occasionally shows VTK(?) variables

This is not urgent at all. Posting here just for awareness:

I have run into a few cases when the information panel shows a variable named Pedigreelds (see below) or Pedigreelds together with another variable starting with VTK. (I saw that VTK... variable yesterday but cannot remember which data file triggered it.) Here is the state file for the screenshot: quickview-state_info_panel_Pedigreelds.json

area is another variable to not show. We should only show the fields that have been user selected.
