Author field isn't displaying

Hi. 

I have a reference listed as “Statue” in Endnote, but I need to change the referene type to “Legal Rule og Regulation”. Problem is, when I’m changing to a different type the author field is not displaying, so basically Endnote won’t let me insert author anywhere while editing the reference. If I create a new reference, the author field does show, but not if I edit the reference type on an existing reference. Also, creating a new reference will be a lot of work because of the document’s lenghts and severe number of in-text citations.
