Hello, @horacio1972,
We suggest that you attempt to temporarily disable any caching and cache plugins, clear the browser cache, and then check again.
If you are able to see the changes in the Customizer but not on the page front, it is likely a cache issue. If it is working correctly in the Customizer, it should also be working on the front end.
Please watch this complete video we have captured for you in which we showed that the changes have been applied and working properly on your site: https://www.veed.io/view/892a810a-4699-43d7-bd21-c3df6ac980f8?sharingWidget=true&panel=share
Kind Regards,
