Disable "A CUE" by pressing and holding the Auto Cue button until "A CUE" disappears from the screen.
Then, navigate to the Menu button and select "Auto Load Hot Cue: OFF". This will prevent the CDJ from loading older tracks and allow it to resume loading normal cues.
To re-enable Auto Cue, press and hold the Auto Cue button until "A CUE" appears on the screen in red.
