Reference level for output mode comparators defined with R85 and R90 is too high and the MCU is detecting "UR" mode for output voltages as high as 1.8 V. This issue is happened because V+/-V- from IC4 are set with inappropriate values of R20 and R25. Therefore 316K instead of 330K should be used. To avoid introduction of one more resistor value, R13 can be also lowered to 316K.
