Updated status but invoice status not updated

Hi! I edited the orders from Pending to Delivered.
However when i want to print out the invoice, it's still showing the Pending on the status...

Can anyone assist me?

THanks!

What settings are you using on the Orders Status for whether you display on the Invoice and Packing Slip the FIRST Orders status or ALL Order Status ...

Configuration ... Shipping/Packaging ...

Display Order Comments on Admin Invoice
Do you want to display the Order Comments on the Admin Invoice?
0= OFF
1= First Comment by Customer only
2= All Comments for the Order

Display Order Comments on Admin Packing Slip
Do you want to display the Order Comments on the Admin Packing Slip?
0= OFF
1= First Comment by Customer only
2= All Comments for the Order

1 will show the Customer Comment and Initial Orders Status

2 will show all of the Comments/Orders Status settings that the Order has on it ...
