min(value) does not update when transform filter is applied in layered chart

Question

Because of this issue, I was trying to make a boxplot with a filter selection manually. The problem is, when I select a boxplot first, it is displayed correct, but when i select another option first the boxplot is wrong My example in the editor

when_selected_first

when_another_option_is_selected_first

I figured out that q1() and q3() are changed everytime I change my selection. But min() and max() stay the same and the problem only occurs in layered charts. Why is that the case?
