Box Engineering Teams have confirmed resolution of this issue. Users who see a banner displaying "Retention and Automations Enabled" should either refresh the Box Web Application or logout/login to a new session. This issue is confirmed to be only a UI display issue. At no time were these policies enabled on an account which did not already have them in place. Please contact us at https://support.box.com if you continue to experience any issues.

Some customers may see a banner reading "Retention & Automation Enabled" in the Box WebApp when this setting is not enabled on the account. Refreshing the page removes this message. Our Engineering Team is actively investigating.
