Ah, I see. He had the time display set to "Playlist elapsed/Total". It's working correctly.

It starts off with his first song entry being a song of 2:14 in length. Then he enqueues a second song, thus making the total playlist time be over four minutes. When he presses "Next" to advance to the second song, the time index starts at 2:14 because it's the playlist position (the end of the 2:14 song).
