Describe the bug When copying to Excel/CSV a result with a subquery where "Hide Object Columns" has been selected, pasting has incorrect data. The information appears correctly in the "Data Export" table, but not when pasting it outside.

For example:

Example 1 (subquery on Orders):

Here is a screenshot of the the results I see in the Data Export tool:

However, when I copy it into Excel I see some values that don't belong to those columns (the Ids that are out of place seem to be coming from the "LastModifiedId" column):

I attach the Excel file here with these two Ids highlighted: Example 1.xlsx

Example 2 (2 subqueries, Orders and Contacts):

When I copy it into Excel, some of the values of the Contacts subquery appear in the Orders subquery columns:

I also attach the Excel File: Example 2.xlsx

When copying the data from the Data Export tool when "Hide Object Columns" is NOT selected, the information gets copied correctly to Excel.
