Find the difference between two dates from two different tables

I am looking to find the difference between two dates from two different tables. The tables being used are Assignments and AssigmentBaselines. The columns used are 'Assignments[AssignmentActualFinishDate] and 'AssignmentBaselines'[AssignmentBAselineFinishDate]. The tables have a relationship many to one (*:1) and has a both cross filter direction.

The formula I have been using is: 

Baseline Days +/- = DATEDIFF(AssignmentBaselines[AssignmentBaselineFinishDate], RELATED(Assignments[AssignmentActualFinishDate].[Day]))
 
The error I keep getting is "Too few arguments were passed to the DATEDIFF function. The minimum argument count for the function is 3."
 
I have looked through many different forum post and I have tried many different ways to solve this issue but I keep coming up short. Any help would be appreciated.

I am no longer getting any errors, but the data is not auto filling into the columns. Screenshot 2023-06-07 121726.pngScreenshot 2023-06-07 121722.png

I guess it just took some time. As of right now, it seems like that fixed the issue. Thank you for the help. I was banging my head against the wall for too long.

This is a bug in the latest update. Just manually resize the column and the values should appear.
