GettIng stuck in UIT.

Here after the last XOR gate i have a condition like if the condition is true then go to the third node from left which is a UIT. 

Here also I am doing the assignment of the UIT to the process initator so that the form will open immediately also doing the enabling the activity chaining ,but it is not happening as expected it is getting stuck here only like the image below.

Can anyone tell me what I am missing here ?

Thanks In Advance !
