A workaround exists while it is not fixed:
For example consider the tutorial "Beginner's guide to Construct 2"
Its URL on the first page is : construct.net/en
If you click to go on the second page it becomes : construct.net/en
But if you modify it to be : construct.net/en you can access the translated page
Each time you want to access a new page, change the number after "page-" to access it and you should be able to go through the whole tutorial without issue.
