My combination rekordbox, DJM-750MK2 and Technicks1210MK2/timecode-vinyl does not work

I installed rekordbox for the first time after purchasing my new Pioneer DJM 750MK2. I work with Technicks record players and the timecode vinyls. Everything works perfectly; the installation worked perfectly, the last update went smoothly, the DVS gives a nice signal, music plays when I put it on via recordbox... but rekordbox does not respond to my timecode vinyl. When i move the vinyl, nothing happens. Because of this I can't mix via my technicks.
