There is no trick. I think your doing it wrong. Take the blue/blue white pair at the station end. Skin back, put 1 clip on 1 blue and the other clip on blue/white. Make sure they don't touch each other.
At the future patch panel end, take your probe and touch securely the cut end of each cable till you find the tone. There should be no spill over this way.
Time consuming yes but it will work.
