LinkedIn not updated

Hello,
 
I have sent invitations for leads to connect through LinkedIn.  The CRM information under that lead does not show the same information on that appears on LinkedIn.  For example, I send an invitation to connect through the CRM and the person accepts.  In the CRM LinkedIn profile, it does not show them as a 1st connection where if I go to my LinkedIn directly, it shows them as a 1st connection.  It has been several days since that person has accepted my invitation.  Any idea why this is happening?
 
Thank you,
Diane
