Attributes of the entry + post templates

Hey. The theme is great. However, I have a small problem with him. I installed the Custom Post Templates plugin in WordPress (https://pl.wordpress.org/plugins/custom-post-template/) to create custom post templates in which custom fields will be placed. Creating templates works. I created my own single-name.php file (according to the instructions) I copied the template-parts folder and the post-order.php files and the newly created post-name.php in which I put the code from custom fields. Everything is tested, but the Attributes of the entry option is not working: Full width, Title and content only, Title and content only without sidebar. How to create a post template for these options to work?
