API Variante anlegen SQL Error

Hallo zusammen,

ich versuche in einen Shop Variante anzulegen, in meinem Testshop neueste Version geht das 1a, in dem anderen Shop bekomme ich allerdings folgende Fehlermeldung (SW 5.5.1.0):

{"success":false,"message":"Error message: An exception occurred while executing 'INSERT INTO s_article_configurator_options (group_id, name, position, media_id) VALUES (?, ?, ?, ?)' with params [13, \"Small\", 0, null]:\n\nSQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '13-Small' for key 'group_id'"}

Das seltsame ist, ich sehe den Eintrag nicht in der Tabelle. HAt jemand ne Idee? 

Hier mein Variant Json was ich auf eine Artikel ID putte:
