Binding Printing

(I am using AI 27.1.1 |  Single document with 8 artboards, all entered the correct 8.5(width) x 11 (height), Portrait in the artboard dialog box) 

I have a odd printing issue. When printing I select the long-side binding and print the pages. The first and last page prints short-side binding and the 2 center pages print correctly as set in the dialog box, long-side binding when printing all boards at the same time. Even when I print those first sheet/last sheet independent, (pages 1-2 and again pages 7-8), "long-side" binding, it print short-side binding. ???? So I tested the selection by printing the pages 1-2 with short-side binding and it still printed the short-side binding (as it should with that selection). Regardless of what I select, I get the first 2 pages (front/back) and the last 2 pages printing short-side binding on both selections.

ANY Help?????
