LinkedIn API returns Positions without Title

An user of our app has noticed a problem with LinkedIn, he has 4 positions and 2 of these positions get returned without an title:

Also the connection profile seems ok:

I even logged in with his LinkedIn profile to check that he has filled in everything correctly and as far as I can see he has.

For retrieving the data from LinkedIn I am using the following gem: http://ift.tt/1elMcHP

And running:

• Ruby 1.9.3p551
• Rails 3.2.19
