XDJ-RX: Bug? Sync not working + Slip-mode bug

Hi guys,

I've purchased one of the new XDJ-RXs. I spent a couple of hours with it and so far it's a cool controller, but there seems to be some bugs on it:

I'm using firmware 1.3:

• Sync ist not working. By that point I mean SYNC (including sync of beatgrid). All tracks I use are analyzed on rekordbox, however it just sync the speed of the track (BPM Sync). Just in like 1 of 10 cases it also syncs the beatgrid. BPM sync is working fine instead.
• Weird bug of slip looping only on right deck. When I got a track playing on the right deck, enable slip mode and do a 1/8 loop with the performance pads (holding shift + the right button) it stops the track on releasing the performance pad. Then I need to press play twice to get it running again. The strange thing is: this occurs only on the first try of the loaded deck. Once I got it running again, slip loop world fine. No issues on left deck.

I hope you can help me because these bugs are really annoying. (If helpful I can also do some example vids)

Thanks a lot in advance.

Best regards
