Frank,
Sorry for the delay. First, can you try registering with your test user on our demo site below? Then, visit the CB Profile url on the left side and see if the information imports:
www.sourcecoast.com/jlinked/registerlogin
I did it a while ago on that site, but my profile cam through just fine (birthday isn't there because it's not in my profile):
www.sourcecoast.com/jlinked/your-communitybuilder-profile
If that doesn't work, can you share the link of the public profile for the LinkedIn user so we can see what it looks like?
Thanks,
Alex
