So in QB Time it is tracked as HH:MM.

When I generate an invoice in QBO it shows as a quantity.  So 03:30 shows as 3.5 in my view of the invoice.  That is correct and the way it should be.

When I send a customer an invoice it shows as 03:30  The header says QTY so most people would assume that to be 3.3 hours.  Why can't this be corrected?  

If it is going to show HH:MM why wouldn't it say that on the invoice header instead of quantity?
