JD Edwards didn't keep notification subscription

Hello community.

I am trying to test the Notification feature on Orchestrator. I created one just for test, and tried to subscribe to it using my user. It seems that it worked, but when I close the screen and enter again, the subscribe disappeared.

I tried to test the Notification just after I did the subscribe (without closing the JDE screen for subscriptions), but when I clicked the "Test" button, it showed an exception about no one has subscribed to the notification. I tried to share the Notification UDO and test it with another user, but the result were the same.
