Report change-medications

When I run the Medications report in report dashboard medications that have been corrected and noted to be entered in error or changed to patient refused show on the report with a given date and time but when I go to the MAR they are crossed through and not actually given. Also have noted that medications that are scheduled at or close to midnight come to the report with the actual time but the scheduled time does not flow to the report.

I use this report to monitor how early or late the medications are given each month so it's time consuming to manually go back and forth to the MARs to verify these things. Can this report be corrected or do my staff need to do something different when documenting in the MAR?
