'DATEDIF Excel - output incorrect

I am attempting to calculate the difference between two dates using Excel's DATEDIF function. When I attempt to do so, I get an incorrect output. I am wanting the difference in days, but the output is way off

How can I fix this? I am trying to get the difference in days - e.g., 26 days

I tried the formula and was expecting to receive the output of 26 days
