Language mixed after changing url

Hallo,
After changing the url of the website from my testsite to the definitive url, my yoast working area has different languages. I used the german language. And now the description of the analyse is english and not more german.
For example, the title is german and the description is english. The Owner of the website need the german version, like before the change of the url.
