Hello @marciomarim. Thank you for sharing your feedback with us and the WordPress community. In most cases, the notices should go away on their own. However, in some cases object/database caching can cause them to stick around even after being dismissed.
Usually, rebooting the webserver will reset object/database caches. Please give this a try, and if you continue to experience problems, contact us at [email protected]. Thanks, again, for your feedback.
