You may need to remove the bulbs and verify the proper bulbs have been installed. The vehicles with the lighting modules and bulb out indicators typically measure the resistance of the bulb to verify function. If the bulb is not replaced with a proper bulb of the same number, you will get the indication that a bulb is out, even if all are working. If you have recently changed a bulb, go there first. While bulbs may look and fit the same, they have different brightness and resistance characteristics. Start there first. Unplug the bulbs when inspecting and check for corrosion which may change the resistance characteristics.
