Find Most Recent Date Relative to another Date Column in Power Query

I'm assuming that the dateAdded: 1/4/2016 12:11 for Max Date Reported: 9/14/2015 is a mistake given the max dateAdded is 12/20/2017 14:05 like for the two other Max Date Reported groups.

let
    Source = Original,
    PreSort = Table.Sort(
        Source,
        {{"contactId", Order.Ascending}, {"Max Date Reported", Order.Ascending}, {"dateAdded", Order.Descending}}
    ),
    LocalGroupFirstRow = Table.Group(
        PreSort,
        {"Number", "Max Date Reported"},
        {{"FirstRow", each Table.FirstN(_, 1), Value.Type(Source)}},
        GroupKind.Local
    ),
    CombineGroups = Table.Combine(LocalGroupFirstRow[FirstRow])
in
    CombineGroups

Thank you for pointing that out my mistake.  The dateAdded for the Max Date Reported  of 9/14/2015 should actually be 3/13/2012, so the result would look like this:

I do not want the score/DateAdded for the Max Date Reported of 9/14/2015 to be 12/20/2017. The score must be the most recent one based on the Max Date Reported.

Thank you!
