Rent out Customer Order invoice is not moving to Invoice closed status

HI All,

I have an issue in the Rent out process flow.

I created a rented out customer order and it delivered to the customer. I started the rental and ended the rental and generated the rental transactions. 

Then I created the customers return and returned the part in the Inventory.

I created the customer invoice and rental transactions are invoiced now. But my rental customer order is still not invoiced closed.

• I checked all the rental transactions are invoiced.
• Part is returned to the inventory.
• No any pending transaction to Invoice.

Is there anything else that I need to perform to bring this to the customer order to invoiced closed status. 

Is anyone faced this issue previously?

Thanks,

Chamath
