Why is there is no way to skip forward

I have done a few courses before but it’s been some time now since I last logged in. I had just started on CSS when I left but now that I’m back I have to restart everything from the beginning. There is no way to skip forward. Why is that? (it says on my profile that I have badges and complete courses, but there is no way to press anything in order to continue where I left off).

It also happened to me with the JavaScript course.

I found out that the problem was the interface language. I started and made progress in the course with Portuguese, but when I tried to access again the course from the point which I stopped my interface was in English.

If you didn’t change your interface language or something like that, I have no idea of what may be the problem.
