Minor bugs have been fixed in theme components and a 2020 blog slug.

• What is the current behavior? (You can also link to an open issue here) This might be causing theme issue in prod but I'm not sure since I cannot reproduce that bug.

About the slug you changed, this would change the permalink of that blog. We shouldn't do that.

The slugs may not be unique as the permalink is /{category}/{slug}.html.
