XDJ-1000 Stutters on first playback

When first playing a track from USB, my XDJ-1000s stutter at the beginning of the track. They only do this on the first track that is played after bootup, and only in the beginning.

I can reproduce this every time, as shown in this video: https://www.youtube.com/watch?v=7roJy6qJzkk

Is this normal behavior?

I have firmware version 1.05 and my USB stick is a Kingston Datatraveller 100 G3 64 GB. Both XDJ-1000s are linked directly together using one of the provided ethernet cables (no switch).
