Hello @Dinesh-gowdam-2610
The same case with me.
But i have been fixed it by creating an extra python class for resetting the all slots immediate after successful submission of the form. And it works fine 
class ActionResetAllSlots(Action):
def name(self):
return "action_reset_all_slots"
def run(self, dispatcher, tracker, domain):
return [AllSlotsReset()]
And i have been added it at the end of my form rule as below…
rules:
- rule: activate document search form
steps:
- intent: lookingfordocuments # intent that triggers form activation
- action: document_form # run the form
- active_loop: document_form # this form is active
- rule: submit form
condition:
- active_loop: document_form # this form must be active
steps:
- action: document_form # run the form
- active_loop: null # the form is no longer active because it has been filled
- slot_was_set:
- requested_slot: null # All the required slots have been filled
- action: action_submit
- action: action_reset_all_slots
Also, registered the action in my domain.yml. Thanks
Best Regards, Ravi
