Why can't I see certain items in a document or a report, even though I selected the folder?
In case you cannot see certain items in a document or a report, you most likely have filter(s) running.
Check in your DOC item whether you have certain filters on and correct if needed. Please note that if you select more than one filter, this is a AND selection, which means all flags should be set on for items to appear.
Check in your project whether you have set the correct filters.
