I have a exported copy of my Contacts, most of which are in iCloud. Using the Contacts import function I Import the contacts. They all show up for a moment, but before I could click on one they vanish.
I also have tried, under system preferences, to uncheck iCloud's contact feature, reboot and tried to enable the feature. Nothing on this approach.
Any feedback would be appreciated.
