Hello --
When I do a drag and drop of the selected files and folders, the contents immediately start to get copied over rather than my being prompted, and there being the option to generate a script within the dropdown menu.
OK, you must have disabled confirmations of drag&drop operations.
Either enable it again:

Or use menu or keyboard shortcut instead of drag&drop.
