Hi Anonymous 

Not sure why you need after Group by however You can perform in same step as below

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXL29wWShgZKsToQAdeIECBphBBw9vdBCBiBVPiBVBgjBDBVwM2IBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ID = _t, INFO = _t, VALUE = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"INFO", type text}, {"VALUE", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"ID"}, {{"AllRows", each Table.SelectRows(_,each Text.StartsWith([INFO],"C")), type table [ID=number, Info=text, Value=number]}})
in
    #"Grouped Rows"
