This system message:
Display title ... was ignored since it is not equivalent to the page's actual title.
is disruptive and should be fixed/deactivated as soon as possible. As the code of the system message is added on the same row as the first row of the article content, it breaks the infobox/table as that always should start on the first position of a line.
Second, also this kind of messages are not suitable to the general public, and should not be shown to them. Like with other messages (like Pages using duplicate arguments in template calls) the message is shown only with editing.
Third, as there is no tracking category implemented, it is not possible to know where this code issue is present and message is shown and where to fix.
