Email connector - header row error

Hi everyone!

We have set up an email connector and added the rules as below:

HEADER ROW - 16

STARTING DATA ROW - 17

Update method - replace

This is because the rows above 16 contain report summary data which are not required in the dataset. However, whenever the automated report comes through from the connector, we are still seeing rows 1-15 considers - which is causing the rows to display as below:

Can anyone advise how to correct this, so we have the header row as "Day,Month,Year,etc"?

Thanks!
