Reply to Help please - Traktor Tempo Faders on Dn-MC6000

G'day,
I am still getting used to Traktor so I just need some reassurance really. I used my DN MC-6000 and a Midi-Fighter 3D.
If I use auto sync and want to bring the track back to it's normal tempo, as soon as I touch the tempo fader it changes instantly to 0%. I would prefer that it allows me to adjust slowly if needed. The 0% position on the Mc-6000 has a "click" so you really can't miss it.
Am I correct to believe that I need to go into the mapping for the controller and change the "Interaction Mode" to Relative or do I change the "Option" to Soft Takeover.. or do I do both?
Any help greatly appreciated.
Coops
