Kategorien löschen - Fehler

Wenn man Kategorien löschen möchte kann man entscheiden ob Dokumente mit gelöscht werden soll en oder nicht.

Wenn ich mich für ja (Dokumente löschen) entscheide funktioniert es einwandfrei.

Wenn nein sollte es ja nur die Kategorien aus den Dokumenten entfernen. Dies funktioniert nicht und es kommt folgender Fehler:
