DRV8701: Quiescent current and heat Issue

Hi team,
I made a motor driver which is almost identical to the reference design. (see schematics) The circuit works fine except it's quiescent current is much more than expected. Quiescent current was determined by subtracting  the current consumption in sleep mode from the active mode. No load, EN and PH pins driven to low. The calculated current is 16mA. (VM=24V) Obviously 24V*0.016A=384mW generates some heat. The catalog data shows 5mA(TYP) 9.5mA(MAX) quiescent current consumption. VM is a 70um inner layer plane, GNDPWR is a 70um bottom layer plane.
Q1: What can cause the abnormal current consumption?
Q2: Using R507, R508, R511, R512 resistors is a good practice, useless, or bad?
