Error or Bug ... in SYNC mode. XDJ RX2

XDJ RX2 (Fw. 1.35 Stand alone mode)

The error occurs when you start a song in SYNC mode, in Beat.
When you press play on the second Deck with this mode activated, it is synchronized with the first one. This does not happen if the SYNC mode is used with LOOPS in both decks.
While there are two loops on each deck, it does not synchronize on the beat
If they are without Loop, only in play, if it is synchronized in the beat.

Thanks and best regards
