Chrome bag strap help

I have recently bought a Chrome Citizen bag from a friend, and i like it pretty much so far. But the one thing bothering me is the long excess strap. It seems like the plastic buckle at the end, is supposed to take care of this. But either i am too stupid to figure it out, or it is in someway not sitting properly in the buckle.

I have attached pictures and a drawing, trying to illustrate the problem. On the drawing the black part is the buckle seen from the top, if it was "cut in half" and the blue part is the strap.

It seems to me that the strap was previously fed in and out of the buckle. But i cant seem to figure out how.

Thanks in advance

In the aerial photo you've taken the excess strap needs to be fed through the top hole. You'll probably find that it still flaps about so an elastic band will be helpful

Thanks! This worked, but for some reason it wasnt tight enough for the webbing to slide out after being tucked in.

So i fed it back again, but through the lower hole this time. Causing it to overlap the stitched part of the webbing. Now its loose enough for quick adjust, and tight enough to prevent it from sliding around.

Hope this makes sense in my crappy english. :)
