Hi Steven,
about which version of Mixxx you are talking?
Removing the track from the Auto DJ playlist when the track starts to play
and not when it is loaded is an intended behavior.
This gives you most control over the play list if you try to manually
interact with the auto DJ.
For example:
* Track A is playing in Deck 1
* Track B is paused in Deck 2 Just loaded on by
* Track B is on AutoDJ playlist top
* Track C is second track on the Auto DJ playlist
It is now perfectly clear what will happen next:
1: without interaction
* AutoDJ will start Deck2 and remove Track B from the list
* fades to Deck 2
* Load Track C to Deck 1
2: pessing fade now (Bad track playing or too long)
* just like 1. but now
3: Double click on a track D somewhere in the library (urgent whish)
* Track D is loaded to Deck 2 displacing Track B
* Remember: B is still on Auto DJ Play list Top
* AutoDJ will automatically start D in Deck2 and Track B stays on Auto DJ
Top
* fades to Deck 2
* Load Track B to Deck 1
-> Advantage: Track B is not lost
3: Right Click Add to Auto DJ Top/Bottom
* Track or playlist is moved to Auto DJ but without moving Track #1 in Auto
Playlist, because it is already likely loaded
4: Shuffle
* Tracks in Auto DJ are shuffled but without moving Track #1 in Auto
Playlist, because it is already likely loaded
It might that you hit a bug do to the previous Library locks.
I have fixed a bug some tim ago that had similar effects you might see.
Is your Auto DJ play list consecutive numbered, starting at 1?
But anyhow, locking track 1 if it is the same that is already loaded and
paused seems to be reasonable.
You should also know that we have a advanced AutoDJ version in our
pipeline.

It was done during GSoC 2012, but it was not maintained since then.
There are still a couple of bug waiting for fixing and refactoring is
required.
But I think that this will be the base of the next AutoDJ Version.
Kind regard,
Daniel
