Live Feed profile displays old name

After a user changes their profile name, the old name is still displayed in their Live Feed profile.

1. Log in to a base system Helsinki instance as an ITIL user.
2. Navigate to Self-Service > My Profile.
3. Change the First name (for example, ITIL10) and click Update.
4. Navigate to Collaborate > Live Feed.
5. In the Live Feed profile, the old name is displayed instead of the new name.

This issue is happening because the live_profile table still contains the old name. Deleting this record should resolve the issue. Afterward, once the user triggers a chat a new record will be created with the new name, as updated in the sys_user table.
