CDJ-2000NXS tempo drifting after 1.40 firmware update

Just updated all of our decks to 1.40 firmware (from 1.35). Noticed the BPM readout going back and forth between 122.8 and 130.0 on some tracks. The deck seems to be "unsure" what tempo rekordbox analyzed the tracks at. Also, if even they are synced, this issue is still occurring, as well as loops not staying locked to each other.

BTW, the loop issue where they drift apart has always been a CDJ-2000NXS issue for me, I just have to push the track a bit with the jog wheel to keep them locked.

Anyone else noticed this?
