Label Printing After Cluster Picking

Hello AxMates

I have an issue about Ax 2012 Wms Module. 

I am using cluster picking functionality on ax WMS module. my work template lines include; pick, Print and Put. I am using this work template for cluster picking. When my cluster is done, my work do not get close. it's status is waiting in process because of print step.

I checked WhsLicencePlateLabel table. any label hasn't created about my work. What should I do for my work get closed and my label be created?
