Modify Buyer Workbench Tree View in Kinetic

I’d like to modify this tree. I’ve poked around a bunch, done some searching…I believe this section may be where it’s intended I make changes, but there’s nothing to edit here. The checkbox seems to do nothing and the Show Columns is empty with no additional options.

I read here that there was an update in 2032.1 for this, but I can’t find any details in current Application Studio guide or online for this.

I’m hopeful I’m just missing something simple.
