Hello,
Seems you have the Mobile theme plugin activate, when you install and activate the Mobile Theme plugin, your pages will be overwritten by the plugin (the mobile theme comes with its own templates for page, post, category, etc so your current templates from the desktop theme will get converted to the mobile theme layout, the page content is made without builders in mobile editor => https://www.screencast.com/t/xbgZG8kH also, the options that are provided to edit the mobile theme version are limited (this keeps the things simple)).
Usually, the problem is from a cache plugin, because you are using the mobile theme plugin, the mobile layout will have a different design and most of the cache plugins do not recognize this and provide the mobile version for desktop (or vice versa). We recommend using WP Super Cache plugin with the settings from our guide -> https://forum.tagdiv.com/cache-plugin-install-and-configure/
Also, please do a test using only tagDiv plugins, clear all cache and see if the problem persists.
Thank you!
