Trying to add "Documents incorporated by reference text block" in the 2018 DEI Updated taxonomy. Every time I try to add in the outline, it asks whether this is a level 1, 2 or 3. Whichever level I choose, it doesn't recognize the DEI in my outline and always asks me to create a new DEI outline. So I create a new one and everytime, it tells me "Error, the target outline section could not be identified". I've tried validating the project and document, sometimes, it resolves on its own.
Any idea how to add this tag? It seems to be required if we have this section in the 10-K.
