Hi @sergnovak, welcome to the community.
The applications there are commonly used apps. You can also use this area to search for apps. You can not delete them from here. They are not duplicates, just shortcuts to common apps. I am not sure what it says in Russian, but in English it says "Local" meaning these apps are installed on your phone. You can set it up to give you recommendations for apps from Google Play based on your app usage.
The second image shows all apps that are installed on your phone. You can uninstall apps from here if you wish, but not any of the pre-installed applications.
