Distillation problem

If all the pre-towers are filled with liquid and the pressure rises, while the pressures and temperatures in the subsequent two towers remain normal, what is this phenomenon? Why?
It’s okay if there’s no relationship; just keep learning*··············
The pressure in the pre-tower has little to do with the two towers behind it. As for what it means to be entirely liquid?
With a high liquid level in the pre-tower, the pressure will naturally increase; this will not have an impact on the two subsequent towers for the time being. However, if the liquid level in the pre-tower is too high, it can cause damage to the trays in that tower; as a result, it is necessary to lower the liquid level and increase the feed rate to the latter two towers, which in turn affects the subsequent operations.
