Any idea why my instrumentation amplifiers decide to fuck with me when the input signal is switching polarities?

I'm using a H-bridge driver (square wave) to drive a coil and am measuring current and voltage signals over it (pic related only shows current measurement)

I have no idea why this happens. Any guesses?
If I put a resistor instead of a coil everathing is fine, the output is a square too
