How to have the Next button at the bottom?

Hi

I checked your examples at here: https://w4dev.com/wp/w4-post-list-examples/?utm_source=wp-admin&utm_medium=plugin&utm_campaign=w4-post-list#examples

In Examples 1 and Examples 2. There is a Next button at the bottom. I added exactly the code to my site but there is no Next button, nothing

What should I do?

Thanks
