Power Query: Import Multiple Excel Files from Folder can't see 3 new columns

[SOQLee]

PROBLEM: 3 new columns had been added to my DATASOURCE tables and I can't see these new columns when refresh my data sources via Power Query. I have imported multiple Excel files from a folder, so went back to check the steps.

When I get to expand 'Tables'. I have a 'GetExcelData.Hidden' column. Is this the reason why I am not seeing my 3 new columns?

GetExcelData.Name	GetExcelData.Data	GetExcelData.Item	GetExcelData.Kind	GetExcelData.Hidden
DATASOURCE

<thead>
</thead><tbody>

[TD]DATASOURCE
[/TD]
[TD]Sheet
[/TD]
[TD]FALSE
[/TD]

</tbody>

UPDATE: solved. When you expand the Table. You need to UNCHECK the box for "Use Original Column Names as Prefix".
