Shuffle Play issue on new Djay for ios 2018. Repeating songs

On the new Djay for ios, I have the full subscription running on the new iPad Pro (3rd gen) and I notice that in automix in shuffle play, it repeats some songs over and over and sometimes never get to many songs in the playlist. Even if shuffle is off, it plays some songs in succession, but stops and starts over in the middle of the paylist! Why is this and where are the settings to avoid this ever happening?
