Standard Fields Not Editable After Posting

Hi All,

We're trying to edit our Job Information fields after the requisition has been posted.  Typically, these fields are editable and allow us to repost the job on the Career Section with any changes.  Currently, we can only edit our User-Defined Fields on this section of the req; the Standard Fields are all non-editable (see screenshot below).  Also, even if unposting the job, there are no changes.  Is this a BUG, or have I been missing something that these fields aren't able to be edited?  I don't recall ever having seen this before.
