Modal Page Not Refreshing the list page when finish running business process

Hello, i am now trying to add in a button called re-appraisal

you know that when you add in a record you use the open new record and it has a pre-configured setup using a modal page to input data and inserting it

now i am trying to do the same with re-appraisal but this time by autotaking a pre-existing data from an item inside the list that was filled out previously

now when i lead it to that page, it goes to this page

like so... now when i press the Re-Appraise button in the modal page, why does it still stay on screen and not auto-refresh the entire list?

this is the business process that is running, do i need to add it in here or do i need to change it from the front?
