Why won't this loft mirror OR pattern??

In the attached 2010 SW file, I'm trying to place the loft at the ends of all the cylindrical features. I've created one easily enough, but when I try to mirror/pattern this feature, I get the message "unable to create contour geometry; please check the loft section."  If I can create it, why not do the other steps??? GRRR!
