Please help - error quest

Hi, I apologize for mistakes in my English in advance, but I have a problem with BDO and quest line, I did a quest about Valencia, and I had the items combined and I could continue like this on the next quest, but I managed to join before I have accepted the task and now I cannot complete the task, this is the Aakman quest on the Valencia quest, and again I cannot do the quest, is there no way to fix it? What should I do to complete the task? Or is it possible to fix it? Please help ...

 

throw away the item you combined, and retake the quest is my solution
