@Anonymous,
You would need to add a step in Advanced Editor to check if the type of the value is record and then expand the record.

There is an example for your reference:

let
    Source = Table.Combine({jsontest, Table4}),
    expand1=Table.TransformColumns(Source, {{"Value", each if Value.Is(_, type record) then _ else [a=_] }} ),
    #"Expanded Value" = Table.ExpandRecordColumn(expand1, "Value", {"name", "age", "maritalStatus"}, {"Value.name", "Value.age", "Value.maritalStatus"})
in
    #"Expanded Value"
