I do not understand why under the category field at the end of a post, categories will appear where they do not belong. For instance:
Categories Bookclub, Doughnut Economics
< The Answer to Climate Change is Democracy
> From GDP to the Doughnut
“Bookclub” is the parent category. The post “From GDP to the Doughnut” belongs to the child category “Doughnut Economics” that belongs itself to the “Bookclub” one. The post “The Answer to Climate Change is Democracy”, on the other hand, belongs to another category entirely; so why is it mentioned here?
