Netbeans gui builder - output different at run time

I am hoping someone can help me.

I am programming a GUI (and program) in netbeans and have run into a weird situation whereby what the application looks like in netbeans preview is NOT what comes out when I run the file - instead an older version of the GUI is displayed.
I include jpegs of the screen shots showing this phenomena but do not know what code I would need to include that might be an explanation for this behaviorAttachment 3378Attachment 3379.

I have cleaned and clean and build the project and rebooted the computer but this action persists.

Please help!!
