Responsive settings are not visible on Frontpage

Hello,

I noticed a little problem with the responsive settings of the pagebuilder.
Changes can be saved and are visible in the backend, but not in frontend. I deleted the caches. I´m using Jommla 3.9, PHP 7.2 and the Pagebuilder 2.2.11.
The URL I can not post here unfortunately, because the site is still in work and password protected.

I would be very thankful for help.

Hi
please contact me by email to give me your url, so that I can check the problem
