Hide screen not working in preview

[soccer_paradise]

Hi-
I’m trying to set up my site across different screen sizes and I’m having an issue with the preview. I have selected the screens I want hidden and they don’t show like they are supposed to live, however they still show in the preview. Is there anything I can do to fix this? It happens in the header/footer builder as well as the normal content. I have flushed my cache and checked plugins. Screenshots attached.

Hi there,

Please make sure to check for the following first:

• We’d recommend that you increase your memory allocated to PHP if you haven’t done so already. To increase it, please edit your wp-config.php file and insert these lines:

    define( 'WP_MEMORY_LIMIT', '256M' );
    define( 'WP_MAX_MEMORY_LIMIT', '512M' );

• If the issue is still there, please make sure that you have everything updated to the latest version especially for X and Cornerstone. You can find more info about the support versions of X and its bundled plugins here.

• If you are still seeing an issue, please try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

In case the issue persists, please provide us with the admin details of your site in a Secure Note (key icon below your response).

Thank you.
