Thank you I understand now.
Unless the menu is part of the actual page content in the editor, then the match is coming from somewhere else. The plugin looks in the database, not the printed content itself. The usual suspects can be selected custom fields (if any), or taxonomy terms (categories, tags etc..). Fin
If the menu in the footer is actually built to the page itself, then you can still try using negative keywords: https://i.imgur.com/zCVUGVS.png
