DDJ-RZ CUE monitoring/PFL & soundcolor effect

How to hear the soundcolor effect on channel 1-4 (after pressing CUE-monitoring/PFL) on the DDJ-RZ mixer?

When i play a track at channel 1-4, apply a sound color effect and want to pre fader Listen / Cue-monitoring the channel to hear the effect i don't hear the effect being applied over my headphones.

The signal flow diagram shows that a soundcolor effect is applied (1) before Cue-monitoring (2) takes place. Then comes the strange part... again soundcolor effects are applied (3) on channel 1-4, after CUE-monitoring/PFL.

Whats going wrong?  (Firmware is updated & using Rekordbox 4.0.7)
