Apple Pages: Copy/Paste Problem with Endnote X4

Hey there,

I’m using Apple’s Pages ('09, 4.0.5) and Endnote X4.

I’m currently working on a paper and have collected a number of quotes, all indicated with Endnote Harvard Style. Now, whenever I move a quote around the document using copy/paste, the author and year ‘element’ (e.g. Smith: 453) becomes normal text and the respective item disappears from my bibliography. After I have pasted the quote including the reference, I then need to enter the respective reference again using cmd+shift+e. This isn’t a problem with a number of quotes, but I’m working with 300+ quotes at the moment.

This might be a really basic problem, but I’d appreciate your help!
