Short form of reference in subsequent footnote?

I’m using Endnote X1 on a Mac, running Word for Mac 2004. For two custom reference types based on Chicago A repeated references in a subsequent footnote omit Author and <Short> Title, giving only cited pages. “Use short reference” and “include short title” are selected in “repeated citations”

Is this a bug, or am I doing something wrong?  Is there any way to fix this?
