Do you mean that you have a whole page for each item or are you only seeing one item?
If you only see one Item, then I'd check the filters in the Item dataitem, in the DataItemTableView property, and also if there are any filters in any of the triggers.
If there's just one Item per page, then check out the NewPagePerRecord property of the dataitem.
