The offset of the ADC sampling value of the MKM34 chip varies with increasing temperature

The mcu is kinetis KM34. I use the AFE module to current sample, but the offset varies with increasing temperature even if I shorted the AFE_SDADP and AFE_SDADM. Is there any way to solve the problem that the zero offset value of the current changes with temperature?
