Wrong subtitles in video tutorial

In material workflow course in unreal academy, the subtitles of videos after the second one are wrongly placed.
It seems the subtitles are shifted in order. I’m not sure because I haven’t finished it yet.
Sorry if I shouldn’t post this problem here, but I can’t find better place to feedback.

There should be a feedback button for each class/chapter (in the lower right-hand corner of the screen). That is probably the best way to give feedback on the class/chapter content.
