The profiles are private, so we'll have to walk you through it.
First, you'll want to remove August-177 as brother of August-176. Go to August-177, go to the Edit Tab, go to the father area and click replace/remove father, at the top, click remove (it will scroll to the bottom of the page), click the big "REMOVE" button.
Now go to August-176. Go to the Edit Tab, go to the children area, click add/remove child, in the box for "A", put August-177 and click Go.
That should do it.
