I am using Lightroom 5.7 standalone ( upgraded from Lightroom 3 Educator) on a PC running Win 8.1. I am importing a catalog into my main catalog. The catalog to be imported is on a laptop running Win 7. All the procedures work Except when I get the selection prompt the option to "Copy to a new a new location and import" does not appear in the pulldown menu. Both other options ( don't move, Don't add) do appear. Where did the "Copy" prompt go? and how do I get it back?
