Your “Films” total counts each film once for the period (all time, or within a single year), while your “Diary Entries” total counts every individual watch of a film. If you’ve logged any films two or more times within the period, your Diary Entries total will exceed your Films total. (Note that a re-watch will still count towards your “Films” total for the year the first time you watch it during that year, but not on subsequent views.)
