Cue point delay, fixes after first press.

I set cue points in most of my songs, to be triggered by my Numark Mixtrack Pro IIs finger pads. I have noticed that immediately after loading a song (using Spotify) my finger pads have a slight delay between my press down and djay moving the play marker to the cue point, BUT only the *first time* I access the cues after loading the song. After the first time I have accessed each cue, the pads then hit the cue point instantly when pressed, until I load another song where the problem repeats. To work around this I have had to load my song, tap all my cue points at least once, then move back to the start cue to prepare to start it. But why do I have to do this?

Same problems with the Beatpad and the DDJ WeGo.
