As for cutting into the laminate, router tilt is most likely the problem, and the solution to that has been posted by Reg66.
You might also try adjusting the depth of cut so the bearing rides just beneath the edging. This way even if the router tilts, it won't be able to cut so much, if any of the laminate.
If those tips don't help, could also be that the bearing is slightly undersized. try putting a strip of masking tape across the laminate where the bearing rides.
