Rekordbox with RB-DMX1 Lighting

My moving heads do not pan and tilt the full 255 even though the setting is set to minimum 0 0, and maximum of 255 255.  I've tried everything I can find in the settings to make it work.  Also the performance is extremely slow.  for example telling it to change colour can take 3 or 4 seconds to respond.  Finally even if it go in to macro editor and change the movement of the light it doesn't save.

Hoping you can help.

The lights are in the DB under:  LED Moving Head Spot (ZQ-B54A) under U King.
