Most of the older songs have been updated with Jam Along videos, but you're right, these ones haven't. We just started adding the backing track videos this year, meaning a lot of going back and reediting existing videos.
Maybe you should write directly in each instructor's forum, and they can easily get in touch with the producer and get it fixed.
