I cannot change the translation options for custom post types this time. The radio buttons are grayed out/unclickable. That's why I am asking and confirm if the below codes are to be added in the same file wpml-config.xlm as your robot assistant suggested for the problem of custom Field control. Understood ? If can change as you said. There is no point I am asking you whether to add.
now for post types control. I just simply put the following code in the same file wpml-config.xlm as your robot assistant suggested for the problem of custom Field control.. Right ?
<wpml-config>
<post-types>
<post-types action="not translatable">_media</post-types >
<post-types action="not translatable">_patterns</post-types >
<post-types action="not translatable">_templates</post-types >
<post-types action="not translatable">_template-parts</post-types >
<post-types action="not translatable">_my-templates</post-types >
<post-types action="not translatable">_variations</post-types >
<post-types action="not translatable">_refunds</post-types >
</custom-fields>
</wpml-config>
