Looks like the friction of the magnet face is too high.
What material do you have on the magnets?

The two magnets need to be very similar in their pull on the axis, such that the axis is suspended vertically, while having a very low normal force into the magnet. The end of the axis should also be polished round rather than to a true point.

Magnets are nickel plated and both came from same manufacturer.

Friction is a problem at all magnetic balancers thus they are not reliable. Are you sure about self centering of shaft axis? Did you mark the center of magnet?

Leaning to one side of a balanced piece is a flux phenomenon, what may be else?

The balancer from TopFlight has ferrite magnets and a plastic disc is glued to the front side. This creates a smooth surface with reduced friction and also creates a little spacing between the axis and the magnet.

Your magnets (neodyne?) might simply be too strong and pull the axis too hard into the magnet.
