there is a problem with a new adm1 in Denmark: Vestsjællands Amt (7498391).
It is not an adm1, and although it appears in searches, the record is not in the database.
yes, there was a bug in an import script and it inserted some records again that had already been deleted. To fix it the records were first deleted from the database and later the search index was updated.
Now everything should be alright.
