As Bob notes
Those magnets might appear to correct things when your camera is pointed north, but when you rotate it, their "corrections" may have nothing to do with reality - the field orientation has changed. And, as Bob also noted, you run the risk of permanently magnetizing stuff in the camera.
So, get rid of the magnets, and start astrotracer calibrations from scratch.
If you have magnetized something in the camera, you should demagnetize it - maybe hard to do with a big bulky item unless you have access to an old-fashioned magnetic tape bulk eraser - something that creates a 60 Hz varying field in which you immerse your object (camera) and slowly withdraw it while the demagnetizer is on. (We used to do this to reels of magnetic tape which were 2" thick and 12-14 inches in diameter.)
