Parent process not waiting for all instances of MNI subprocess to complete, before moving to next node

Hi

I have parent process and a Subprocess "waiting queue". this sub process is configured as a MNI with configuration to "Move on after all instances are done".

However, after each instance of sub process is executed the node following the MNI is executed and its not waiting for all instances of MNI to finish.

Please have a look at the implementation below and let me know if anything is incorrect?
