Do it like you see in the image.
It is not that you type "empty" in the Value field of the ID.
Your current criteria means that:
If the Element is a Door
and the text written in its Element ID field in its Settings Dialog or in the Info Box is both "empty" and "does not contain", then the Door should be listed.
This of course will return zero results because the Element ID of and Door cannot be "empty" and "does not contain" at the same time.
What you should do with the setting I gave you is select all Doors you want listed, go to the settings dialog and delete everything from its Element ID field. Then its Element ID field will be empty (no string or zero string).
If you want all Door except the ones with the empty Element ID then the criterion should be
"Element ID" "is not".
Then Doors with a zero-string ID will not be listed, all other Doors will be.
