Passing a level but saying failed

Rauchm404

Hi everyone!

Currently on level 1318 and passed with my last move (or i should of anyway). Objective is to unlock each box then break them twice. I achieved this on my last move and the game said i failed....why is it doing this?! I attached the picture showing all boxes where cleared (top&bottom). Extremely frustrating as its not an easy level!
