Thats the whole idea of the barlowed laser. Makes it insensitive to laser wobble when you are collimating the primary. Simply take the barlow lens off to collimate the secondary and put it on again to collimate the primary. If the little donut shadow returned to the collimator base is moving about as you move the scope then there is some mechanical flexure there in the system. If everything is tight I'd go to the manufacturer. Maybe it needs stiffer mrimary mirror springs though I'm sure there would be some kind of locking bolts somewhere.

Good luck.
