Hello, @SkalasEyg,
If you are able to see the changes in Customizer and not able to see the changes after publishing it on the page front, then it means you are facing the cache issue only as if it is working fine in Customizer, it should have to work on frontend as well,
Please try to clear the site and browser cache and check back OR try to check the site on any other Computer on a fresh new browser and I am sure you will not face this issue anymore.
And if the issue will still persist then please take the complete backup of your site, first.
And also share your WP-ADMIN Login details in the below-listed format in the private area on which you are facing the issue so that we’ll check and assist you accordingly.
