[Closed] How to save a block without taking over a link from original into translation

Background of the issue:
I'm trying to save my manual translation on hidden link. In one of the blocks, there's a link in the original text that I don't want to include in the translated version. I'm following the documentation on the advanced translation editor.

Symptoms:
I can't save the block without including the link from the original text. Clicking the little X on the red 'a' button does nothing.

Questions:
How can I save a block without including the link from the original text in the translation?
