Odd endnote X2 / Pages 09 thing...

I'm writing a medical article where we have to reference in Vancouver style and superscript. Having dutifully changed the output style in Endnote X2 to superscript, every reference inserted in Pages comes in... subscript. When I try to output in subscript, the references come out with a normal baseline. Everything else (formatting, etc) is otherwise fine. I am at a loss to explain this and would appreciate any help!
