days360 with today() shows different value

Hey Guys,

I need a small help.

Range "K" has the formulae

TODAY()

In range "L" I want to substract range "K" with range "D" using Days360

The formulae I am using in cell "L2" is

DAYS360(D2,K2)

The formulae works well but when range "d" is empty then it shows 42669

I want it to show blank if range "d" is empty


I have attached my workbook.

Please help me
