Items not exported in DOC file

Hi,

I created a view which displays 2 content types (COLLECTORS and NON-COLLECTORS).
I've also created 2 computed CCK field to help me do the sorting.
On the table view, I see the whole list of nodes, sorted correctly, everything looks perfectly fine.
However, when I export it into a DOC file, the sorting is kept but half of the nodes are not exported.

I'm completely lost.

Thanks for your help
