Are you powering both devices from a single power supply or does each device have its own power supply?
Double check the current limit setting on the power supply. The supply current for the ADL5811 is 185 mA, supply current for the AL5387 is 180 mA. You might be current limited and the voltage is dropping giving the appearance of a short. If the circuit has not been modified, there is no possible way I know of that there could be a short circuit path from the ADL5811 power supply and the ADL5387 ground.
