[Gelöst] Translate options goes to page edit in the selected language instead of translator

Background of the issue:
We have a number of pages where the issue occurs. When you are in the WP dashboard in the default language (English) and want to translate, or change the translation of a page, you go to the Pages and select the pencil under the language flag. Normally you will go to the Classic Translator screen. Link to a page where the issue can be seen: versteckter Link

Symptoms:
Instead of going to the Classic Translator screen, the dashboard language changes to the selected language and the page is loaded in edit mode.

Questions:
Why does the translation option go to page edit in the selected language instead of the Classic Translator screen?
