UE4.10.4 is painting entire squraes

So anyway I have my map of Thebes sculpted and textured with the landscape material. I then start on the floodplains along the Nile River before starting the rolling grasslands. It not only textures the floodplain but the entire square. WT* I wonder why it is doing this and what I can do to stop it?

I thought it might help if I posted a picture of what is going on 92b9d114817153c75275dbb99bac8dc1d38c1b12.jpeg

By the way I figured out the problem. It is a program glitch and I will be trying out 4.9.2 when it is done downloading.

Turns out it is not a program glitch and I can’t find any reason why it is doing this. I have followed the instructions on YouTube and the manual for setting up landscaping material.

Well since no one is able or willing to help me than I will have to assume this is a normal function for the engine and that I need to figure out a workaround.
