Tutorial menu links are "undefined"

I am going through Tutorial menu window and I notice that a lot of links (the ones on the bottom, the button with the “play triangle”, the blue boxes under the scripts list and more…) are named as “undefined”. It seems the links are working, but it is like browsing blinded the tutorial… :frowning:

I have DT Pro Office 2.3.5 under ML, but this issue was already present since SL.
