What I expected to happen:

What actually happened:

Hi,

I type in the code and it should be correct after checking with answer. I wonder if there’s something wrong with the system?
Please help me to solve the issue, thank you!

There definitely is an issue on our end here!

Hi @Bruno

It would be a great help if you can help to solve this problem.
I had the same problem in the next exercise as well.
Thank you!

I can’t help you with this, it escapes my powers. But I’ll let Mary (@Mary) know and she can forward it to the right person.
