@JCoronado Is it possible to share rvt file?

Sorry I just saw your message. I have attached the Revit Family I am using and also the Dynamo GraphKeyNotes.dyn (27.1 KB)

CCG_KEYNOTES - Optional.rfa (256 KB)

You’re not comparing apples to apples. You’re filtering the elements by whether Sheet Name has a value, but you’re filtering values by whether the element’s owner view has a Sheet Number.

You can copy the List.FilterByBoolMask you’re using for the values and just replace the list input with the original list of elements.

@JCoronado you just have to filter your elements by family type. Category node which you’re using now is collecting other Annotation families which doesn’t have “SheetName” parameter. This should work for you:
