Hi p.renee,
I was just having a similar problem, when using infinite-scroll with wp_query. It turned out that pagination wasn’t working properly for my wp_query.
Try turning off infinite-scroll and make sure that you can get to the older posts pages.
I found this post very helpful; https://wordpress.org/support/topic/pagination-with-wp_query-and-custom-post-type
Thank you, that’s a good tip 🙂
