Backend - Artikelöffnen - Fehler

Hallo, beim Öffnen der Artikel erscheint ein Fehler. In dem SQL steht unten 2x LEFT JOIN aber es wird keine weitere Tabelle eingebunden. Eig. sollte hier noch s2 und s2 eingebunden werden. Dies ist aber nicht der Fall. Kann mir jemand sagen warum? Ups! Ein Fehler ist aufgetreten! Die nachfolgenden Hinweise sollten Ihnen weiterhelfen.
