Greetings, @Mee1977.

Let me share some information on how QuickBooks handles your invoices.

You'd see the Due column once you convert an estimate into an invoice. This allows you to see how much of the approved estimate was already invoiced. 

The ability to manually remove the Due column when using the Progress invoicing feature is not available. However, you need not to worry, your customers or clients will not see this column when you send their invoice.
