Transforming schedule data

Ok, that was a pretty simple change. Rather than adding 6 days, I just went from start to end.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUbLUN9Q3MjAyAjONYUwDJGyiZwokDeEisTrRShDlhgYw9YZG+sZwcwyxYIRWY4hWI4StRnBrjcBWGWNhQfXHAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Start_Date = _t, End_Date = _t, Monday_Hours = _t, Tuesday_Hours = _t, Wednesday_Hours = _t, Thursday_Hours = _t, Friday_Hours = _t, Saturday_Hours = _t, Sunday_Hours = _t]),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"ID", "Start_Date", "End_Date"}, "Attribute", "Value"),
    #"Changed Type" = Table.TransformColumnTypes(#"Unpivoted Other Columns",{{"Start_Date", type date}, {"End_Date", type date}, {"Value", Currency.Type}}),
    #"Extracted Text Before Delimiter" = Table.TransformColumns(#"Changed Type", {{"Attribute", each Text.BeforeDelimiter(_, "_"), type text}}),
    #"Filtered out Zeros" = Table.SelectRows(#"Extracted Text Before Delimiter", each ([Value] <> 0)),
    #"Duplicated Column" = Table.DuplicateColumn(#"Filtered out Zeros", "Start_Date", "Date Bracket"),
    AddDateRange = 
        Table.AddColumn(
            #"Duplicated Column",
            "Date Range",
            each
                let
                    varStartDate = Number.From([Start_Date]),
                    varEndDate = Number.From([End_Date])
                in
                {varStartDate..varEndDate}
        ),
    #"Expanded Date Range" = Table.ExpandListColumn(AddDateRange, "Date Range"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Date Range",{{"Date Range", type date}}),
    #"Inserted Day Name" = Table.AddColumn(#"Changed Type1", "Day Name", each Date.DayOfWeekName([Date Range]), type text),
    #"Added Match" = Table.AddColumn(#"Inserted Day Name", "Match", each [Attribute] = [Day Name], Logical.Type),
    #"Filtered for Match is TRUE" = Table.SelectRows(#"Added Match", each ([Match] = true)),
    #"Removed Other Columns" = Table.SelectColumns(#"Filtered for Match is TRUE",{"ID", "Date Range", "Value"}),
    #"Grouped Rows" = Table.Group(#"Removed Other Columns", {"ID", "Date Range"}, {{"Hours", each List.Sum([Value]), type nullable number}})
in
    #"Grouped Rows"

So just for ID 3, I get this. Originally 3 was 5 rows, but spanned 2 weeks, so it makes sense to me it now has 10 rows. As you said, ID 2 is dozens of rows...
