Which zip did you download? If they appear different, it could be because it's the 32x32 version, not the 48x48 version in the other zip. We usually build our screenshots directly in the editor so no scaling gets involved. Maybe try the other version and see if it helps?

I downloaded both versions just so I got them. Just for good measure, I deleted the ones from the game tileset folder and copied them over. It's still the same. Also, I notice the top left tree has a transparent tile: https://imgur.com/9RUSCl0
These were really designed as a collection of resources you can pick and choose to add to your own tileset, but it's a pretty simple fix, so we've uploaded a copy that can be implemented directly into the editor. I also updated it to a single zip file using our current naming schemes so it will look a little different than what you had before but should have the same content. Hope that helps!
