BQ77915: UV, OV, OCD Cutoff Issue

Part Number: BQ77915

Tool/software:

Hi,
I'm working on 48V_ BMS with BQ7791514 - 3 staking configuration
1. We are observing under voltgae cutoff at 42.82V and over voltage cutoff at 52.4V, instead of 37.5V and 54.75V respectively.
What may be the cause for this and how to increase the accuracy now?
2. Facing issue with the Over current cutoff, Threshold OCD1 voltage value is at 50mV, I'm defining my over current cutoff at 25A, as per calculation I have placed 2mΩ current sense resistor but as a result the cutoff is happening at 23A.
Kindly support to resolve this issue
