[Closed] Theme Config (Settings) constantly being Overwritten with russian language

Background of the issue:
I am trying to use the WP Rentals theme with WPML to translate my site into Russian. However, my main theme settings are being overwritten with Russian translations. This issue primarily affects the configuration for the Search Forms, making the search function unusable for English-speaking clients. I have a Staging Environment ready for investigation. Link to a page where the issue can be seen: hidden link

Symptoms:
The main theme settings are being replaced by Russian translations, particularly affecting the Search Forms. The English settings are overwritten, causing the search function to be unusable for English-speaking clients. I have to manually restore settings using a backup file, but the issue recurs. Hosting provider confirmed no malware or malicious scripts are causing this.

Questions:
What is causing the Russian translation to overwrite the English theme settings?
How can I permanently fix this issue so that the Russian translation does not affect the core English theme settings?
