Acrobat - Combining files

I have Acrobat Pro DC on both my laptop and my desktop. When I use the combine files tool on my laptop, Acrobat works the way it is supposed to. It combines the files into a binder.  When I use the combine tool on my desktop it doesn't create binders, it creates "portfolios" and doesn't do what the combine tool does on my laptop.  How do I get Acrobat on my desktop to work the way it does on my laptop?

Thanks,

Gary
