So I've made a post and put it under 3 categories. Drama, Romantic and comedy. But when I go to reviews and all my categories appear, I can't click on Romantic or Comedy. I have the same problem with other posts. It looks like post only appear under one catergory instead of multiple. When you click on sci-fi you'll see the post is put under different categories but you can't click on this under reviews.
The blog is in dutch, but it should be easy to notice.
The blog I need help with is watchandtellblog.wordpress.com.
