In shuffle everything(not sure which shuffle mode), I press tweek order and get the message "match found", but no change is displayed in the now & next display. In fact the next song has not changed.

In this particular example i tried tweek artist and tweek album, neither worked. I noted that the tweek by title didnt work, but I am not sure if this has ever worked. I see in Tony's button guide that this is lable "future functionality". So thats probably expected not to work.
