lost records

I have a problem. Some records are visible in a ‘query, fast search’ but not in the folder where they are supposed to belong. Even more records appear in the word add in which do not exist in any folder including many linked to PDF attachments. Generally these records have been created by ‘trial user’. Overall there seem to be 3 people listed as creators. John, Whicherjohn and trial user. How can I find and merge these records?

A reference has to belong to

A reference has to belong to a folder. In the preview panel, "Read" tab, the folder a reference belongs to is listed in the second line. When a record is created, Biblioscape will stamp it with the Windows login name as the creator. This will not affect anything. There is no need to merge them.
