    Paste the below code on in the Advanced Editor on a Blank query and check the steps, All done using GUI.

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUVKK1UFiJCEzKuCsYjgrFc4qArOSYRpSkBklSrGxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Module = _t, Function = _t]),
    #"Replaced Value" = Table.ReplaceValue(Source,"",null,Replacer.ReplaceValue,{"Function"}),
    #"Grouped Rows" = Table.Group(#"Replaced Value", {"Module"}, {{"Count", each List.Max([Function]), type nullable text}, {"all", each _, type table [Module=nullable text, Function=nullable text]}}),
    #"Expanded all" = Table.ExpandTableColumn(#"Grouped Rows", "all", {"Module", "Function"}, {"Module.1", "Function"}),
    #"Added Custom" = Table.AddColumn(#"Expanded all", "Custom", each [Count] <> null and [Function]=null),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([Custom] = false)),
    #"Removed Other Columns" = Table.SelectColumns(#"Filtered Rows",{"Module.1", "Function"})
in
    #"Removed Other Columns"

    In Power Query, Click Get Data, Choose Blank Query > Go to Advanced Editor in View Menu > Clear all that is there and paste my code.

    Now you can check the steps on How I solved it.
