Click the top-level SiteNavigationElement (not the ItemList). The table is pretty clearly wrong (as shown in the screenshots, but copied here for readability).
| key | value |
|---|---|
| @type | SiteNavigationElement |
| url | next page -> |
| name | https://forum.bors.tech/latest?no_definitions=true&no_subcategories=false&page=1 |
The URL and the Name should be swapped.
