Hi Adwin,
That is strange. My colleague added another simple page, and it shows that usage of the Classic elements is the issue. The Text element works correctly, but the Classic text element does not.
I checked my installation, and that is not the case, but my installation uses an older version of the WPML plugin. So, as you did all the tests and we did what we could for debugging the conclusion is that the version of WPML you use is not compatible with the theme.
We will double check the case with our development team, but at the moment, the official supported version is mentioned here. I do not have any means to know if that is the case as I do not have access to the latest version of the plugin to check.
If you can be kind and upload the latest version file somewhere and link it in a secure note we will double check the case with the new version and our installation to see if this is a version compatibility case or not.
Thank you for your understanding and cooperation.
