Problems with URL's from the friend page to lesson videos

The link on the lesson page to lesson videos doesn’t work.

Example:
alleray just added a Deutsch video for Österreich und seine “Sprachen”, Wien - (Deutsch).
The link is: http://www.lingq.com/learn//store/56419/119532/buy/

But there is “de” missing (the language). The following link is correct: Login - LingQ
