[Resolved] Problem with post types and templates after copy the site

On the previous page, we had plugins installed: WPML Multilingual CMS, WPML String Translation, WPML All Import.

After copying the site to another domain, we disabled the plugins and removed some of the posts or templates we had previously created. We created new posts and templates.

Now after turning on the plugin, the templates and added post type disappear. We can see that the actual number of templates or posts is shown when we click on "All", but they are not visible. When we turn off the plugin, everything returns to normal.

We tried to remove the previous translation completely according to these instructions: https://wpml.org/documentation/getting-started-guide/language-setup/deleting-languages-and-plugin-data-by-doing-a-wpml-reset-on-your-site/#step-1-remove-the-secondary-languages-and-all-existing-translations

Unfortunately, in step one after clicking on the delete icon to remove all the content, nothing happens. The loading wheel loads endlessly.

We have made a full backup of the site, so we can provide accesses to the site to locate the problem.

We would like to either remove the translations and plugin completely and install WPML from scratch or leave the current settings, but with the post type and templates display correctly.
