Custom WP_Query don’t work for administrator

For one of my categories that is restricted with uam groups I have created a page template in which I have a custom query. When I am logged in as administrator I can’t see any post in this category page, but if I am logged in as subscriber with access to this category I can see all post in the category page. This has work before and not sure when it stopped working, don’t know if it is after upgrade of wp-core or plugin.

Do you know if there has been any changes in how I need to define my custom query?
