Learning Records Subject Area - How to remove duplicate lines

Summary:

In the new Learning Records Real Time Subject Area, I am trying to produce a report for the following data, but when I add the Activity Details start and end time, two records are produced for a few employees.

How do I only produce records with the correct data?

Content (required):

Without Activity Start Time

With Activity Start Time

I need the Activity Start Time for Instructor Led courses, but there are no Activity Start Times on Self-Paced courses, so have used the Offering ILT Activity Details for Instructor-led courses

I need to display both Delivery Modes.

Could there be two completion dates with different times or is there another explanation?
