"Enroll" button is not showing for newly created life event

Summary:

I have created a new explicit 'Benefit Admin' and attached the life event to the program. I have also set the rules as follows:

• Enrollment code: Current - Keep only; New - Nothing.
• Default rule: Current - Same enrollment and rates; New - Nothing.

This setup should restart rates and coverages from the original dates. However, on the enrollment screen, when I try to add the life event, it moves to the "Processed" and "Closed" state instead of displaying the "Enroll" button.

How can I resolve this? What do I need to enable to make the "Enroll" button visible?
