Pull down resistor 1.3V, 1.8V Domain

Looking at 3 different power domains of AD9361: 3.3V, 1.8V, 1.3V

When powering the device with those 3 voltages, an extra pull down resistor on 1.8V and 1.3V is required. Otherwise the voltage on the 1.8V domain raises to 2.8V (measured).

 

What is the optimum pull down resistor when having only the AD9361 in the 1.8 and 1.3V domain.
