TOPIC: Editing field items when pressing BACK button

I'm sure I'm missing something in some configuration/permission setting so I'm hoping someone can remind me:

When a logged in user registers for an event and the process takes them to the page containing the message:

Please check the data below and confirm that everything is correct. If so, click the NEXT button. If not, click the BACK button below and make the necessary corrections.

Trouble if, when they go back the fields are not editable.

BTW: Using Community Builder for users

Also, Is there a way to bypass that second confirmation page? and go straight to confirmation?

Thanks!
