Here's how it works...
If you have LOAD LOCK enabled, it prevents the user from loading a new song to an active deck. This means the playback is moving.
When you play a track and it hits the "end" of the song, and you don't have the AUTO PLAY enabled (meaning the next track would automatically begin playback), the deck stops ... and allows you to load a new song, but the state of the deck is still PLAY, even though it is stopped at the end of the audio file.
My suggestion -- if a song is over, even if you've let it run to the end, BEFORE you load a new song, pull down the fader for that channel. It's not playing any more, why leave it up? THEN load the song, so if it starts playing, your audience won't hear it.
We have already reported this back to the engineers, but it's not really a bug so much as an unintended method of operation.
