It is possible that the cookies on your cloned site are not translated immediately. This is probably because the cookies are loaded from an external source.
Because the cookies are loaded, the text cannot be translated with the editor, as it cannot access them. You will then have to use substitution rules to adjust the text in the cookie notification. Often this is enclosed, for instance with
<span>. Always check the source code first to see how the text in the cookie notification is enclosed. You may have to use several substitution rules to translate all the individual parts of the cookie notification.
