SM 9.52 codeless - Change does not move to next phase when all tasks are closed

Dear Experts,

I need your help please.
SM 9.52.
When I was using SM 9.30 this feature was working properly. When Last task is closed: "close this phase" action was working perfectly. Now in SM 9.52 PD codeless, this feature doesn't work. 
Can someone tell me if it is a bug? I don't want to create a script since we have this functionality OOB. 

Please let me know.

Thanks
