How are Duster side pop-out windows held in place?

[71Twister1owner]

My 71 Duster was recently painted and all window gaskets replaced. The side pop-out windows are now too low and they drag the metal below the window when opened. How are these windows held into place and what can I do to keep the leading edge of the window from sliding down? (It seems that they now can slide up and down a small amount). Is there supposed to be some kind of sticky strip installed under the chrome to keep them in place?

eV2 - I didn't do the work so I don't know if the stainless railing was lowered. Any suggestion on how to get instructions on tearing the window down so I can try to figure what's wrong? There's a vertical chrome piece on the leading edge of the window that I probably need to remove - but it isn't intuitively obvious how to get it off.
