WCK posts translation issues (WPglobus)

Yes, it is version 2.3.6.

Hello, with the Classic Editor plugin I can also see the WP globus options.

It should work also with Gutemberg editor. In the editor of standard pages and posts, it works also with that.

There is also a setting where you specify which types of posts use block editor: /wp-admin/admin.php?page=wpglobus_options&tab=compatibility

Sure, this is my code.
