Any way to input MRT in CBE Thermal Comfort Calculator?

I am trying to study the effect of solar radiation to thermal comfort using CBE Thermal Comfort Calculator.
I used SolarCal function and got the delta MRT as below.
However, this MRT is not reflected even pushing Adjust MRT.
Also, I cannot find any interface to input MRT even though it is shown in the interface in [help page] ( as below.
Can anyone know how I can reflect the calculation result from SolarCal?

If you click on the EN-15251 button in the top right-hand corner of the CBE Thermal Comfort Tool then you have the option of entering air temperature and mean radiant temperature separately. Alternatively, you can use Appendix C of ASHRAE 55 to calculate the operative temperature based on the air temperature, mean radiant temperature, and relative air speed. Appendix C does note that in most cases, the relative air speed and/or the difference between mean radiant temperature and air temperature is small. In this case, the operative temperature can be estimated as the mean value of the air temperature and the mean radiant temperature.
