DS won't calibrate correctly on one side of the screen.

Hi! I've recently switched out the bottom screen of my DS because it was dying. The replacement screen however seems weird. Input is a lot to the left although I touch somewhere on the right. Calibration isn't working properly and only lets me go round and round for eternity unless I misinput on the bottom right point or entirely, but that's not the point of the calibration.

The left two points are always rightly calibrated, but the right ones are either very far to the left or to the right. The screen and rims are clean. Can someone help? I don't want to waste any more hours on the calibration screen :(
