Hey there,

I am really sorry for the delay of this reply as it is a public holidays for us here.

I think Payplans 3.x doesn't have this feature but we did implement this in Payplans 4 (you can refer at my attached screenshot below), you should consider to upgrade it.

By the way, you can try execute this following SQL from your database and see if it showing the correct result for those user subscription already expired.

Remember replace jos_ to your table prefix.

SELECT `a`.`id`, `a`.`username`, `a`.`email` from `jos_users` as a 

	inner join `jos_payplans_subscription` as s 

    	on s.user_id = a.id 

            AND s.status in (1603) 

            group by a.id
