How to identify if an Element is there or no ? (Element Exist is not working here)

How should we identify if element is there or no ?
I want to check below if something is there.

Want to check - Sometimes claim amount is also available in dispute amount …
I tried Element exist but not working, I tried Data extract but somehow that column is coming blank even something is written there.

what was not working? Can you share more details also to the application type?
