harvested crop sale

In the crop drop down box in my harvested crop sale, I have 2012 corn and 2011 soybeans and spring wheat that are listed but no location is shown or bushels exist in harvested crop inventory. I physically have any of those crops on hand. Is there a way to eliminate those crops from the crop drop down box? What might I have done in order for those to show up like that?

Thanks,
Pat
