Incorrect order status

Hi.

My completed orders have a wrong status in status summary and I can't fix it.

First, my settings:
In Settings/Options/Processing Order Status : I checked : Completed and Shipped.
In Settings/Options/Complete Order Status : I checked : Completed.

2nd, the status of the orders I have a problem with is "Completed".

Now when look at the summary of the order status (bellow the menu, on the left side), the completed orders are included in both Completed and Processing orders percentage. It doesn't make sense to me. It should be in Completed OR Processing, not both.

Anyone can help?

Thanks in advance

Which summary? Where exactly?
