XDJ700 Linked with CDJ2000Nexus instant Doubles is not working correctly

I 2 X CDJ2000Nexus, 1x XDJ700 and a DJM2000. I using the XDJ700 as a extra deck. In the future I will buy another XDJ700 so I can practice me 4 deck skills at home. The XDJ700 is a very nice player and its working correctly with me CDJs 2000Nexus. Only I have a problem with the instant doubles is not working on my XDJ700. if one CDJ2000Nexus is playing a track and I copy the same track to my other CDJ the instant doubles work. when I do that to my XDJ700 it start playing at the beginning of the track. When the XDJ700 is playing and I copy that track to one of the CDJs the CDJ isn't even playing that track instantly. Can Pioneer fix that?
