BQ34Z100 LEDs button fail on discharge

Hello!

Batt is 8800mAh 4s4p.

Following problem:
During the charge, remaining capacity is displayed normally on the LEDs by pressing the button and in  bq Eval Soft.
But then the discharge current is applyed the, second (first is ok) stroke to button causes all LEDs on, and data transmission through the EV2300 stops (i2c comm), and looks like controller freezes (not sure coz )...
So, only 1-3 times re-applying discharge current makes LEDs turn off and back to EV2300 data comm.
Also, its changes the value  ​​of the 'Remaining capacity' of the field in Data Ram ( from 50% to 85% for example).

Pack is calibrated.
Looks like I missed something during cofiguration.

Useing Figure 8 unchanged (except vlotage devider)
Here are my settings for BQ34Z100.
