Repeating Table Headers - XML spreadsheet

When copying data from Excel we are using XML Spreadsheet from Paste Special to create a table which works great. The issue is repeating the header information, even after selecting the top rows and changing the type to Header, the headers will not repeat when the table breaks is enabled.

If a blank table is created to see if the functionality works, it does, just not with XML Spreadsheet data.

Any idea what could be the issue?
