1031 Exchange Form Issue

I am having an issue filling out the 1031 form (8824). I sold farm land and purchased another farm. When I fill out the form, everything is calculated correctly but when I get to line 25, it only gives me the choice to put a basis for section 1250, 1245, or intangible property. It is my understanding that bare land is none of those choices, it should be section 1231 property. It is forcing me to put a value into one of those choices for me to continue. Is there a work around for this?
