Ignore my post above about the “warning” section.
I have done a lot of writing and fixing site errors after updates and have a much better understanding.
The warning displays after a field has its code altered. You can close the warning in the backend and it will NOT appear again until the frontend of the website is visited on a page that has the offending field which then re-triggers the warning.
You must know what page each of the warnings is on.
make your code changes,
close the warning in the WP dashboard
reload the page on the frontend that had the field with the code stripped (if you fixed it, all should display properly)
Reload the dashboard and that warning should be removed from the warning list or not display at all if that was your only warning.
So removing or hiding the warning (at least for admins) is not a good idea and my code above is not recommended.
