Reinstatement Rule not working

Summary: When an employee moves through the self service screens forgetting to add their spouse initially, the exit out of the self service enrollment screens and add their spouse. When they go back to enroll the newly added spouse, they get an error saying they must enroll in at least one option in plan. See screenshot here:

The defaults are set up for this plan.

When I run the evaluate life event process in evaluation and reporting, it will process the life event completely, but will not enroll the person in the plan option. When I go to look at the enroll in defaults child process report, there is no error. And when I look at the evaluate life event log, it is finding the employee is eligible for the option, it's just not making the default enrollment. This is only happening when the life event has been evaluated, and then is backed out and re-evaluated when a spouse is added.
