World creation buttons remain highlighted after clicking on them

When clicking on the world type button in the "World" tab, it does not become unhighlighted after clicking on it until you go to a different tab.

How to replicate:
1. Go to the "Create New World" screen
2. Go to the World tab
3. Click on the world type button (or any toggleable button)

EDIT:
This bug applies to every toggleable button in the Create New World screen
