Here is the date diff calculation I'm trying to calculate:
DateDiff('day', TODAY(), [Last Sent Date])
The format of Last Sent Date is as follows (Screenshot attached):
Standard Short Date (Date & Time)
Any idea why the result is always NULL?

@Noah Berko Unless there is something odd going on in the filters, I'm not sure why it is returning NULL. You can put TODAY() on the Rows shelf to verify that Tableau is returning the correct date. If you have already, close Tableau and reopen it to see if the problem goes away. If not, try recreating the workbook from scratch.
