When searching, Command+[Number] opens a folder in Finder (rather than navigate into the folder), even though in Alfred's preferences>File Search>Navigation, "Use [return key] to open folders in Finder" is unchecked.
Strangely, when I run "Previous Path", the Command+[Number] navigates into the respective enumerated folder, which is the behavior that you'd expect. I tried checking and unchecking "Use [return key] to open folders in Finder" and restarting Alfred, but that doesn't resolve the issue.
