[נפתר] Duplicate language doesn't use custom text for a link, instead uses page title

Background of the issue:
I have EN-US and EN-CA languages. EN-CA is duplicated based on EN-US language. When I add a link to one of my subpages and use custom text (e.g. "Explore this feature"), then this is ignored in EN-CA page. Instead, EN-CA page uses page title (e.g. "Subpage title") for the link text. Please help me. Link to a page where the issue can be seen: קישור נסתר

Symptoms:
The custom text for a link is not being used on the EN-CA page. Instead, the page title is used for the link text.

Questions:
Why is the custom link text not appearing on the EN-CA page?
How can I ensure the custom link text is used instead of the page title?
