[Закрытые] WPML overwrites my page content in secondary languages

Background of the issue:
I am trying to edit a Latvian page, which is a translation of a Lithuanian page on my site. My site's main language is Lithuanian, and I also have pages in Latvian and Estonian. When I edit the Latvian page, the URLs inside it get overwritten. For example, I write the URL /produkta-kategorija/romex/ in the Latvian page, but it gets saved as скрытая ссылка. Link to a page where the issue can be seen: скрытая ссылка. I expected to see: Romex Instead, I got: Romex

Symptoms:
The URLs in the Latvian page get overwritten when I try to edit them, resulting in incorrect URLs being saved.

Questions:
Why are the URLs in the Latvian page being overwritten?
How can I prevent the URLs from being changed when editing the Latvian page?
