Comment page count is wrong

Couple examples to illustrate:

Spider-Man: Brand New Day says it has 23 comments as I write this. The site indicates there are 3 pages, but if I count up page 1 it has 20 comments. Page 2 has 3, and trying to go to page 3 just doesn't do anything. https://wetrakr.com/movies/683168?comments_sort=new&comments_page=2

Fast X has 12, and displays a pagination widget at the bottom with 2 pages, but there is no Page 2. All 12 comments appear on Page 1. https://wetrakr.com/movies/305606?comments_sort=new

Seems like the site is counting pages as if there are 10 comments per, but displaying 20 per.
