The 3 Date/Time columns in the Seat Type Report include a "Z" at the end of the value (ex. 2025-11-11 00:07:27.000 Z). This prevents the field from being used as a date without manually removing it or creating a helper formula to remove it. Please remove the Z from the date/time in Last Paid Activity (UTC), Last Login (UTC), and Date Added to Org (UTC).
