Broken Page with Posts template in Aspen theme

We have a range of pages that we would like to pull appropriately categorised or tagged posts into. We have created the pages under https://soilcarbon.org.nz/?page_id=65 and changed each page template to “pages with posts” and entered the appropriate categories and tags that should be accumulated under each section.

We have specified that they be sorted in descending order by date and a max of 10 per page in each case.

However, although there are relevant, correctly tagged posts for most of the pages, they are not loading in any of the pages except one, https://soilcarbon.org.nz/?page_id=125 however, none of the posts being loaded to that page are relevant to the tags or categories for that page.

Anyone have any ideas what is wrong?
