For many years I have been adding a copyright date and text string to each of my scraps and survey centrelines.

Always the same text string, and the date according to when the scrap and centreline was created.

Always with the same result – a statistic in the pdf export that includes the string and a date range.

Just now I broke with tradition, and added a new string to a centreline.  To my surprise the new copyright did not appear in the output.

After a little experimentation I have come to come tentative conclusions.

1. Copyrights added to survey centrelines are not added to the statistics in pdf exports that include only survey centrelines.
2. Copyrights added to survey centrelines are not added to the statistics in pdf exports that include maps.
3. Copyright strings (different to the majority) added to scraps in large projects may not be added to statistics in pdf exports.  In smaller projects they are however.
4. Copyrights sorting in the pdf output is unpredictable. 
   It is not according to spelling A to Z, but changing the spelling changes the output sorting.
   
   
   It is not according to date, changing the date does not change the sort order.
   
   In all these examples, there are a number of scraps with “NZSS” as the copyright string, and there is only one example of the other string (“NSG” or “caves.org.nz” respectively.
   So the sort order is also not related to the number of instances of the same string, because sometimes NZSS sorts first, and sometimes last.

Any one have insights or experience with this?
