Gryffindor 

Regarding sudden changes where some nobility or royalty paraphernalia is added/changed into the articles, these are the trademark of user Gryffindor, nee user Antares, also formerly user Bhinneka and user At-whatever. The said person has attempted to add styles and titles to a vast number of locations, and also attempts to "make things consistent" in that regard. You have faced an influx of "von" additions to names which are perfectly capable of living without von. There are certain signs that the aforementioned user is somewhat neurotic, as she soon erases comments from others that questions her actions.
