Value of my formula goes to 0 when applying ArrayFormula with added condition.

Initially I used:

`=ArrayFormula(max(if(Simplified!$B$4:$B$267=$K$2,Simplified!$E$4:$E$267)))`

to find the maximum value with one condition.

It works but when I added another condition which is

`=ArrayFormula(max(if(AND(Simplified!$B$4:$B$267=$K$2,Simplified!$K$4:$K$267=$K$3),Simplified!$E$4:$E$267)))`

it returns a value of 0

Help would be deeply appreciated!
