home 7 Monitor Problem

From vinyl and external mixer i´m used to be able to use the crossfader for the outgoing signal and the monitor for ...monitoring.
Doing so in mixvibes, the crossfader cuts the monitor signal of the right player when moved all the way left. The same thing happens opposite direction too. (I forgot to mention: Yes, I do use two soundcards, one for the outgoing signal, one for the monitor)
Further more there is no display 1/2 under the monitor button as in the demonstration video.
Is there a failure or a hidden secret?
Would anybody be so kind and help?
Greetings
