On the profile for Cunningham-9227 both his father and his mother have been marked as "confirmed with DNA". There is a DNA confirmation statement in the sources starting with the words "Paternal relationship is confirmed by ...", so there is no problem with his father being marked as "confirmed with DNA". However there is no equivalent statement starting "Maternal relationship is confirmed by ...", so that is what is producing the suggestion.
If you add a DNA confirmation statement explaining which DNA tests have confirmed his mother, just like has already has been done for his father but starting "Maternal" instead of "Paternal", then that will fix the suggestion.
