How do I change the default values for posting to Careers Websites in Requisition Posters section

Summary

Check boxes for 'Post the requisition on External (or Internal) Careers Website now defaulting to checked

Content

Our recruiter has reported that when using the job library to create a requisition the check boxes for fields 'Post the requisition on External Careers Website' now shows as checked by default when the Requisition Posters section opens. They report the boxes were unchecked in the past. How can I change this back? 

They are also reporting that even if leaving the boxes checked, if they open the requisition it is not posted to the external or internal careers website unless they uncheck and the check the boxes again and save. Has anyone else experienced this?
