Grouping, I'm not getting it

I am trying to create a table that will look like a spreadsheet for the output but because of multiple people and actions - it's duplicating dates, locations and titles for an incident like so:

Date of Incident   Location      What Happened   Who's involved    Correction Needed    Due Date       Status

1/24/2019               Building A   Wires Exposed    Jane Doe                    Fix wires                           1/30/2019    Completed

1/24/2019               Building A   Wires Exposed    John Doe                    Contact Supervisor   1/30/2019   Completed

I want it to look like this:

Date of Incident    Location     What Happened   Who's Involved   Correction Needed     Due Date        Status

1/24/2019               Building A   Wires Exposed      Jane Doe                 Fix wires                             1/30/2019    Completed

                                                                                                          John Doe                 Contact Supervisor     1/30/2019     Completed

I know I'm missing something somewhere but I don't know what.

Please advise.

Thanks in advance for your help.
