That's very strange, indeed. Are you sure you left the fields "Cache location" blank? Or erased whatever might have been filled in there by default (PGC seems to copy the data from your latest search)?
If I run the statistics, it clearly counts all my finds, everywhere. (I have currently a bit more than 5000 finds in Belgium, and as you can see the table shows a bit more than 8000 finds for me, so all my finds wherever on this planet.)
