Water and lava and swamp areas

[Skullos]

I dont get it, once I put down lava or swamp or water, I cannot raise it to dirt again. How can I do that? I cant seem to get rid of it. And if I raise the terrain all I get is just water on a hill, lol....

Anyone can help?

RTFM. Use eraser tool on rivers tab. First choose type of terrain to erase (lava, water, swamp) then below press Erase. Now you can erase this type of terrain.
