I opened https://musicbrainz.org/place/82403c7e-9eb1-4aac-8928-c953066e4cf9/add-alias, selected "search hint" as the type, submitted the form and got the following error.
Copying the name to the sortname before selecting "search hint" does not help.

Error:

Caught exception in MusicBrainz::Server::Controller::Place->add_alias "The edit could not be created.
POST: $VAR1 =

Unknown macro: { 'edit-alias.edit_note' => '', 'edit-alias.as_auto_editor' => '1', 'edit-alias.type_id' => '2', 'edit-alias.name' => 'Museumsplatz' }
