PMIC buck1 output not getting generated completely

I have connected the correct 47K res for VSET1 but I am not getting 1.8V, instead I am getting 2.3V
I am getting the correct output for BUCK2 as 3.3V
I have checked the resistor value on VSET1-- it is 47k

I have checked if any other rail could be back driving the 1.8V rail, but doesn't look like that.
What could be the probable reason ?
