I've attempted to change the track order in the following release (swapping the order of tracks 7 and 8), and the changes look correct in "Track List" and "Recordings" before entering the edit, but after doing so, the original order is maintained.

Also tried making the change and then selecting "Reset track list" but still the problem persists.
