Confirmed using the English language interface. I started with 14 entries on the 1st (and only) page displayed, and then sent emails one by one, until exactly 20 emails were displayed in the page, and just as described above, a second page suddenly appeared - without entries in it. I agree with the original poster; the second page shouldn't be displayed/generated as logically there are only the first 20 entries - which are all visible on the 1st page.
