Out of a total of 8 result rows in view Χάρτης, 1 rows did not have their field_latlon set and therefore could not be shown on the map. The first row that could not be located was row #7 (nid #9250: ΧΡΙΣΤΟΦΟΡΟΥ ΝΕΚΤΑΡΙΑ). You can improve execution efficiency by using the Views UI to add an "is not empty" filter for field_latlon.
