I use "Department" to help identify my contacts. In Department, I have two key identifiers, HS and HS-new. There may be one or two more identifiers in that same Department field. When I do my searches in Contact, I find 38 names. When I conduct the search in MailMerge, I find only 16 names under "HS" and none under HS-new. In fact, when I search for HS-new, it finds nothing. Again, the problem occurs only when filtering in MailMerge.
