Terrain tool changed

I’m working on a school project togheter with my team. We use Git to share the project so everybody is up to date. I’m responsible for the terrain, but since my latest pull from git my terrain editor changed. I also cannot change the brush size with {} (wich i normally could)
Image above shows previous settings, image under is our project

How can I fix my tools? I’m very limited with the terrain now and would like to change it back.
