Only the last row of a Table is carried over when populating a new form using "Create or Upload Doc" step

Hi, everyone!

I have a scenario where the data collected in an initial form needs to be used to pre-populate the same table field in a new step using “Create or Upload Doc”.

When the data being transferred is a table that contains multiple rows, only the data from the last row is successfully carried over and displayed in the corresponding table field. All other preceding rows are lost during the transfer even though it’s there in the input XML variable:

<Witness_Container>
  <Witness displayName="" displayValue="">
    <Name>John</Name>
    <Email>john@email.com</Email>
    <Marital_Status key="Single">Single</Marital_Status>
  </Witness>
  <Witness displayName="" displayValue="">
    <Name>Mary</Name>
    <Email>mary@email.com</Email>
    <Marital_Status key="Single">Single</Marital_Status>
  </Witness>
</Witness_Container>

Initial form: 

 What I see in the Create or Upload Doc:

Has anyone been through this and have a solution? Thanks!
