[otrs] Still getting reminders after the ticket has been closed

Wondering if anyone can help with this issue. A tech will put a pending reminder date on a ticket. Subsequently, they closed the ticket. They still get notifications as shown below, and these seems to keep coming also, despite the ticket being closed. Is there something I can do in admin to stop these pending reminders once tickets are closed? Subject: [Ticket#1100342] Ticket reminder has been reached!
