Problem/Bug VoxelSniper Problems

So I load up VoxelSniper. I enter the server.

"HOLY CRAP I DID IT I INSTALLED VS!"

So then I toy around with it for a bit before I start to build my map. But then whenever I try to change my brush size, it says this:

"Changed Brush Size to: Ball
You specified a shape without an effect" and then it doesn't work.

That's not the only problem. I heard usually that VoxelSniper's default settings sets the brush to 1-Block. When I installed it however, the default settings were made so that the arrow made block edits of a 9x9 radius.

So um... what the heck does that mean? And what do I have to do to fix it?
