    Use this

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUfJ1NwSSBUqxOsj8QjR+ERq/GI1fohQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Competency = _t, #"PI OCA Red" = _t, #"Critical Components" = _t]),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(Source, {"Competency", "PI OCA Red"}, "Attribute", "Value"),
    #"Added Index" = Table.AddIndexColumn(#"Unpivoted Columns", "Index", 1, 1, Int64.Type),
    #"Added Custom" = Table.AddColumn(#"Added Index", "Custom", each [Attribute]&" "&Text.From([Index])),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Attribute", "Index"}),
    #"Pivoted Column" = Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Custom]), "Custom", "Value")

See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test

Try both the codes and see which one is wanted by you.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUfJ1NwSSBUqxOsj8QjR+ERq/GI1fohQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Competency = _t, #"PI OCA Red" = _t, #"Critical Components" = _t]),
    #"Pivoted Column" = Table.Pivot(Source, List.Distinct(Source[#"Critical Components"]), "Critical Components", "PI OCA Red")
in
    #"Pivoted Column"

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUfJ1NwSSBUqxOsj8QjR+ERq/GI1fohQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Competency = _t, #"PI OCA Red" = _t, #"Critical Components" = _t]),
    #"Pivoted Column" = Table.Pivot(Source, List.Distinct(Source[#"Critical Components"]), "Critical Components", "Competency")
in
    #"Pivoted Column"
