If the InDesign layout uses facing pages and you've selected "spreads" in the Export PDF dialog box, then that's what you get - pages in the PDF file with two-up imposition. Changing the view mode in Acrobat will have no effect, you need to re-export from InDesign with the spread option turned off.
I made the corrections as you recommended and solved the problem. I was able to export the PDF and view it in Acrobat as single pages just as you described.
Thank you for your help and reply.
