You really need to have someone check your English. It is very bad and so hard to remember which incorrect translation you expect.
Yes; this has been a frequent complaint.
Some of the odd grammar might be to help students understand how Hungarian forms sentences and which bits of grammar to pay attention to (though it's debatable how far that helps), but some of it is simply odd.
Will you be one of the someones to help check the English?
You can help the course in this beta phase by using the "Report a problem" function whenever you see bad grammar, and proposing a better alternative.
Reporting is more useful than commenting, I think, because reported problems get collected in one place in the back-end - comments end up on scattered sentence discussions.
Nevertheless, thank you for helping to make the course better!
