left and right temperature display at Info, motor in the MBUX

Hello, there are some engine parameters in the MBUX under Info, engine. See photo. I suspect that the right temperature indicator is the oil temperature, and the left water temperature. However, if the water temperature is left, then my vehicle will not get warm even after 45Km distance. If I look in the instrument cluster for coolant, the temperature is at approx. 90 degrees. What is this like with you or what should the left temperature indicator represent.
