If I plead not guilty to retail thief and got disorderly conduct, why is it still showing up as retail thief?

Every state has it's own set of reporting requirements for how charges are initially reported when you are arrested and then how they are updated after a plea.  The process is usually done manually either through a form or on-line data entry-- these means that if you were initially charged with retail theft, the person doing the updating may have only entered the result and just didn't update the change in the charge.  Contact the clerk of the court and the agency who is reporting your charge to learn how to use their dispute procedures for updating your criminal history.  You may also want to contact a criminal defense attorney if either of these is not receptive to helping you.  Some counties are extremely helpful, while others are not that motivated-- but tend to become more motivated when they are contacted by an attorney.  But try the self-help first-- many counties and law enforcement agencies have procedures in place for this specific type of issue.
