ALB seems to be active though "use WP classic editor" is set

Hi
I got a very serious problem which must have occured after one of the last updates of wordpress or enfold.
One of plugins (map plugin) that I am using, by default uses post template for the location detail page. Last time I have tried to add new location detail pages, the layout of the page in the frontend changed dramatically – many of the elements added through loop-index.php and single.php disappeared. These elements that did not vanish, have changed their position. I have tried switchig off all other plugins but that did not help. The wired thing is that all old location detail pages display properly, even if I modify them. But when I try to duplicate a location page or create a new one, it is being rendered as never before. Unfortunately the plugin author does not support the plugin anymore. I would not even ask him for help because I have never received any personal help from him. Maybe I am wrong but it may be the ALB which causes the problem. All the old locations seem to be created in classic editor (editor name near the title of the post on the post list). But when I create a new loction page or duplicate an old one, the editor name is: classic editor, Advanced Layout Builder (though there are no ALB elements in the backend). Is it possible that it is not disabled, though in the enfold settings, under „Select Your Editor”, „Use WP Classic Editor” is set?
