I am unable to reproduce your problem.
My dates are in d/m/y format but that shouldn't be an issue. In D2 of Calculation I have the date 23/10/2019
I was able to enter your formula into the formula bar after selecting cell K2 and the formula, as expected, auto-filled to the other table rows once I pressed Enter.
