DDJ-1000 'D. Echo' sound color fx bug

Hi. I found a bug I could replicate constantly with the Sound color fx. When I select 'D.echo', and slowly raise it from the middle, to the max right side (Not sure if I tried the left side), and then I turn off the fx with the 'D.echo' button, and then I turn the knob back to the middle position (with the 'D.echo' button off), and then turn on the 'Pitch' sound color fx, the track will be affected by the fx, even if the knob is set to the middle position. I tried to replicate it with 'Noise' and 'Filter' and I could not recreate it. It only happens with the 'Pitch' fx. So...

Steps to recreate:

1) Play a track.

2) Have sound color fx all to 'Off' and all knobs to the center position (off right ?)

3) Turn on 'D.echo' fx.

4) Slowly raise 'D.echo' fx to the right, to max value.

5) Once the max value is reached, turn off fx via the 'D.echo' button.

6) Return sound color fx knob to the middle position (Off right ?).

7) turn on 'Pitch' sound color fx.

8) The deck that was affected by the 'D.echo' fx, should be affected by the 'Pitch' fx, even if the knob was set back to the middle position (Off right ?)

I was able to replicate this numerous times. I just got the unit, and did not do any firmware update. I thought I saw Rekordbox DJ updating something, but I'm not sure if it was the unit's firmware. Tonight I will update the firmware. 

Thanks.
