Why do ASPEN simulations show temperatures at the bottom of conventional distillation columns to be over 4000 degrees?

Why is the bottom temperature of the tower as high as over 4,000 degrees degrees when separating propylene glycol and diisopropyl ether conventionally? Thank you, expert
Is it a problem with the physical property method?
Such a high temperature at the bottom of the column should trigger an error or warning; it’s possible that the number of trays set is too high, or there may be an issue with the property parameters used. It is recommended to look for Aspen literature related to the separation of this azeotrope

It’s possible that the pressure and pressure drop settings are incorrect
It’s indeed the voltage drop setting that’s wrong, thank you
