"Sheets" Node as input does not show up in Orkestra input window

General

I could not get the dropdown node “Sheets” do display in the Orkestra input window when running the script. R-Clicking the node and selecting “Is Input” does not make it show up in the list. I am using Orkestra 2.0.0.7

Hey there ! Is that an OOTB node ? Or is it from a package ?

It is OOTB node - Revit > Selection > Sheets.

I also observed something strange:

When I firstly open Revit and open the definition that has this “Sheets” node as input, it wont show up in the Orkestra Input window. But If I then open another definition that has a different node with a dropdown selection in the Orkestra input window, like for example “Categories”, “Family Types”, or “Views”, then close this definition and open the again the one with “Sheets” input then the dropdown shows up.

So basically it wont show up unless I firstly open another definition that has a different sort of dropdown node as input.
