Candidate Profile Edits

Summary

When editing profile, employer and education fields are not "updated"

Content

When I get a request to change or modify an email for one of my properties, I usually have to either edit or add the Work Experience and Education Fields if they are not either filled in or what is in the "database" for the system.  

Is there a way to turn off those the mandatory aspects of those fields?    The Other fields gets all the infromation, but the main fields do not.  

Once I update the email or candidate's information, if those fields are not filled out, it won't save it.   Not all education and work places are included.
