I’m not sure whether or not the track duration update is an autoedit (meaning that it will get applied right away without the review period). In any event, you should be able to change the track titles right away. I believe these will take the standard review cycle. When you change the titles on the tracks, please remember to also change the associated recordings.
In those rare cases where you need something to go through sooner, you can post a request in the thread below to the auto-editors to intervene on your behalf. You can also post a request to have other users review the edit and vote, which can get the edit applied sooner (assuming you get three or more unanimous “yes” votes).
