Unwanted Jagged edges

[Om3n]

Hello all. I'm brand new to Gaia and seem to have this issue no matter what settings, biomes etc I use. I have tried randomizing stamps etc and no changes I make seem to be relevant at all. I've gone through several iterations of new maps and just cant seem to figure it out. There are always thes large jagged edges. Not in a cute way, but in a way that a player would need to become a climbing expert with full gear to get around them in some spots.

 

Any thoughts would be greatly appreciated. 

Thanks!
