DDJ RZ DVS Support

I've recently bought rekordbox Control Vinyl for use with my DDJ RZ.

All software, firmware and driver is up to date as far as I know.

I have 2 Technics 1210 plugged into the back of the DDJ RZ going into the phono inputs.  I can play normal records with no issues but can't get the DVS to work.

I can't seem to get the green circles to come up in the boxes.

Where am I going wrong?
