Very sorry for the delayed response.
Honestly, we've never heard of this issue before. I'm not sure what's causing it, but we'll have to look into it further. Right now, we're no longer developing JLinked and are migrating all users to JFBConnect. There should be the same LinkedIn features in JFBConnect as there were in the last release of JLinked, as well as a ton of other features and improvements. If you haven't already, I'd recommend going to the "My Downloads" area, getting JFBConnect and then following the
JLinked migration guide
to upgrade to JFBConnect.
I don't think that will fix your issue directly.. but it may since, as mentioned, we haven't heard of this issue before. We will test and try to diagnose what may be going wrong with the split name fields though and try to get you a solution soon.
A few final questions though:
* What version of Community Builder are you using?
* Do you have an additional plugins for CB that may be altering how the default profile/registration flow normally works?
Thanks,
Alex
