Phpcms topic paging problems, isn't it a bug-php Tutorial

I recently learned about phpcms. when I was working on a topic, I found that the topic page is always wrong. what is the problem. When I change the data displayed on each page of list.html under the topic template, different results are displayed. For example, if a total of 32 data entries and 16 entries are displayed on each page, pages are normally used. However, if 14 entries are displayed on each page, pages cannot be normally used, the static pages on the first two pages are generated, but the static pages on the last page are not generated. I tried the data several times and found that the last page contains very few data, so the static page cannot be generated. I used the phpcms code directly downloaded from the Internet, and changed the number of displays on each page.
