Trouble Printing PDF Booklet

Hello Adobe Support Community

I have been trying to print a "booklet" consisting of 8-1/2 x 11 size paper, of pages 16-31 from a 45 page .pdf file using  https://helpx.adobe.com/acrobat/kb/print-booklets-acrobat-reader.html  directions.

The directions appear to indicate the booklet pages would be printed by compiling two .pdf pages per each side of 8-1/2 x 11 sheet, printed on both sides, so that a fold will create an 8-1/2 x 5-1/2 booklet printed on every page.

I have tried about 9 times, using all the different print set ups I can see, but each time, except once, the result was FOUR (4) .pdf pages on each 8-1/2 x 11 side.  The one time I got 2 .pdf documents per side, the paper orientation was portrait instead of landscape, and the two .pdf pages were so small that four could have fit, and I couldn't find that setting to try and enlarge or reorient it.  

So by now I'm getting in trouble with wifey for wasting so much paper, I could have printed four full size single sided copies !!!

I'm thinking the solution is so simple I will feel bad for not finding it on my own, but I have wasted so much time I give up cause I can't think of anything else to try.
