Creating new tickets from a CRM layout - Look Up contact field doesn't work

Creating new tickets from a CRM layout - Look Up contact field doesn't work

After integration of Desk and CRM, 

When creating a new ticket from a desk related list in a CRM contact,
the lookup field for the contact name doesn't autofill
and when manually searching for the contact, eventhough apears the contact to select, clicking on it it doesn't fill the fields.

How can we solve it?
