This thread is resolved. Here is a description of the problem and solution.
Translations that were created with the Kallyas page builder are lost.
This theme is officially compatible with WPML and even was retested a month and a half ago.
But its page builder is not fully compatible with WPML. In our documentation at the following link, we explain how to translate pages that are built with the Kallyas page builder.
There also good videos from the developers of the Kallyas theme on how things should be done. You can watch the videos here.
This is the technical support forum for WPML - the multilingual WordPress plugin.
Everyone can read, but only WPML clients can post here. WPML team is replying on the forum 6 days per week, 22 hours per day.
