[Закрытые] Duplicated language variant, but all internal links go back to the default language

Background of the issue:
I'm developing a site using WPML with English as the default language and US English as a secondary variant. I've duplicated pages for the US English variant using WPML translation dashboard. The links on these pages are relative paths, such as /contact-us/.

Symptoms:
After duplicating the pages, all internal links on the US English variant pages redirect to the default English variant instead of the US English alternative.

Questions:
How can I ensure that internal links on duplicated pages point to the correct language variant?
Is there a specific setting in WPML or Elementor that I need to adjust to fix the link redirection issue?
