Help! Foilage Layers!

So I don't know what's happening at all, but when I try to paint foliage on I get literal carpets of grass, I don't know what it is, the Density refuses to go below one. Any help?

And yes, this is from November, I took a break from the SDK & have been going on and off, working on coding & modeling.
