Hi Ahmed, glad to hear it's going well. It's not a problem, test the content as many times as needed. We want to make sure everything is working as expected. Feel free to mention in case something is required from the Smartcat side.
We have released WPML 4.6.7 which includes a fix for the issue reported here. If the update does not show up in your WordPress dashboard, you can update it manually as explained here: https://wpml.org/faq/updating-wpml-manually/.
