Adjusting Expedition 3 piece side straps

[Corvairfan]

I am a bit puzzled on how to physically move the leather in the Expedition side straps. There are the 2 black square rings and there is a silver square ring. It seems like the black rings do nothing but give a path for the belt to go through and the silver locks it down.

But the leather is so tight against the silver ring that I can't figure out how to adjust it.

What am I missing in this? Thanks.

Usually, you just have two black rectangular sliders or rings, standard issue. Any pics? Normally, you just go through the two black rings and over the top of the ring on bottom, then back through the top ring.

No pictures. I wonder if it was an add on piece someone added to hold the strap tighter. The 2 black sliders are still there but sitting on the bottom of it all.

I was looking at Rundquist's photos where he compares it to a US Wings and while both of his sliders appear to be silver there also only appear to be 2 instead of my 3.

I could always use his great photos as a reference and take off this piece. It only concerned me because I have been reading here it might be nice to tweak the straps on occasion.

If you have 3 you should be able to route the strap through and have the end finish pointing back
