Labview cann't display class hierarchy normally

[jhuangy4]

   I am using Labview 2019 SP1 32-bit.

  Currently I found that Labview cann't show a normal class hierarchy. I opened some labview projects to try, their class hierarchy all just show a strange square in center.

  I've also tried to open class hierarchy in Labview 2019 SP1 64-bit in my computer, the result is just the same.

  Would anyone have met the same strange problem too or anyone have method to solve it?😂

Looks OK in LabVIEW 2020 64 bit...

Sorry, not too useful.

Looks OK here - LabVIEW 2020 32-bit. I did notice that your Child class is not a child of your Parent class.
