IntelliJ won't load excercises maybe language problem, how do I change System Language?Hey, so I'm in level 5 now but never used IntelliJ, because it won't show the excersises past Level 2. Is that because my "Teaching Language" is German and the German translation stoppt after Level 2? Is there anyway to resolve this? Like how do I change the Language of all lessons to English?

Level 3, Lesson 3 I click on "verify" and nothing happens. Tried to refresh page couple of times, but it's still the same. Also, in previous task with "repeat the following code" there is no code, just blank space. In the task there is nothing under "requirements".
