[Risolto] Can't complete translation with an internal link in a WPForms checkbox field

Background of the issue:
I am trying to translate a WPForms field with a checkbox that contains internal links. The original (Swedish) checkbox field has this content: När du skickar in din ansökan innebär det att Stockholmsmässan kommer att behandla dina personuppgifter. Information om detta hittar du i vår dataskyddspolicy. Jag samtycker till att Stockholmsmässan behandlar mina personuppgifter för detta ändamål. I have unlocked the URL field padlock and changed the link myself, but that doesn’t help. The issue can be seen here: link nascosto

Symptoms:
I can't complete the translation of this field and I get this message: "The original sentence includes formatting markers. However, not all markers are applied to the translation."

Questions:
Why can't I complete the translation of the checkbox field with an internal link?
Why does another checkbox field with a link in the same form translate without issues?
