Everything was working fine, but now there appears to be a bug within my CMS pages.
On my site, if one navigates to the blog page and clicks on a category at the top, the collection below in the related post section is showing the same post for every blog post. They should all be different and ordered.
The same blog post is shown for all categories!
Within the designer and the preview section in Webflow, it is shown correctly. The page is "Categories Template" at the bottom.
