Custom Alerts No Longer Bring Event Message in Alert

Yesterday I updated our ELA to build 11201, and today I discovered that our custom alerts no longer include the event message in the alert emails. For some alerts this is not a big deal, but for our alerts such as "user locked out" it's important to know who is locked out and who was unlocked.

When I review the alerts in ELA I no longer see the option to include the event message. I vaguely recall a checkbox option that used to be there, but it's been quite some time since I had to work on these alerts so I could be mistaken.

Is there a way to get the actual event message included in the email alerts again? I'm hoping this is something simple I just don't see. I appreciate your time and assistance.
