Deleting users from elasticsearch but still appear on assignees

Hi, Is this intentional to delete users but still appear on assignees panel?

For example, i have user named “hytam” on elasticsearch (I previously deleted already) but still appearing on assignees.

In users page, there’s nothing user named hytam but on Security > Alerts > Assignees, it’s still there.

Step to reproduce:

  1. Create random user.
  2. log in into kibana.
  3. logout, and then switch to superuser account (example: elastic).
  4. delete random user.
  5. check on Security > Alerts > Assignees.

Thanks in advance!.

here’s user panel.
