Broken rivers when landscape size is too large

Summary

When I add a river to my landscape, the river has a strange shape. It doesn’t ‘smooth’ properly with the landscape to achieve a nice shape, and then pieces of terrain are automatically generated on one side of the river. I would like to keep the ‘Affect Landscape’ ON as it already is.

These pieces of terrain shift as soon as I move the river or add splines.

My landscape is a default landscape (when an island is created), and I’ve added tiles (17x17 tiles) and it contains three layers: Water, Splines, and Layer.
I’ll provide more information if needed! Thank you.
