[FSE | Full Site Editing] - template is not applied to translated page

Overview of the issue

You may encounter issues with block theme templates, specifically translated template may not be applied to the translated page.

Workaround

• Remove the translated template from the database (wp_posts and icl_translations) OR
• Switch to 2nd language from the top bar and go to Appearance > Editor to find your translated template and delete it
• Enable Slug Translation in WPML > Settings Page URL > Translate (this will include the slug in the translation and not create it automatically from the title)
• Go to: wp-content/plugins/sitepress-multilingual-cms/classes/full-site-editing/BlockTemplates.php and around line 56 comment-out:$postData['post_name'] = $post->post_name;

• Send the template to the translation
• Translate the template while making sure that the slug is the correct one and includes the translated page/taxonomy slug
