Problems with XDJ-RX updated version 1.60

Hi, this is a new owner of XDJ-RX updated to 1.60 they pay.
I have three problems with this console, it states that the whole library and was analyzed by rekordbox and used with a 64Gb SSD verbatim.
1: The machine goes out of sync in both Autoloop is when I do an overlay track (even when you use the Sync function and Quantize).
2: On the left Deck Search key is faulty, or if I keep it down to scroll forward quickly this crashes, so I have to release it again and press it again to advance the track.
3. Sometimes during the DJ sets the play button does not start, cueing makes me feel the track by pressing cue but then when I go to mix the play button will not start.
I hope I explained myself.
Thanks in advance for your time!
