Problem: You are working on a multilingual site using WPML and have encountered issues translating custom components and custom post types created via the 'Custom Post Type UI' plugin. Even after installing WPML and its components correctly, you noticed the absence of a translation stream or queue overview and clear options or workflows to translate custom components or theme-built blocks. Solution: Since you have the Multilingual Blog license which does not include the use of the translation editor, the first step is to make the post types translatable in WPML > Settings > Translation of Content Types. Then, you can translate them using the WordPress editor by clicking on the '+' icon.
Please note that this solution might be outdated or not applicable to your specific case. We highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If this does not resolve your issue, please open a new support ticket at WPML support forum.
