Multiple Terrains Issue

Hello,
I am creating a game and need multiple terrains side by side,
The issue that I am having is when the terrains are side by side (both terrains are exactly the same) there is a small height difference, Does anyone know how to fix this?

E.g When i walk from one terrain onto another my player goes down a wee bit, is there any way to merge the terrain so this does not happen

Any help Appreciated

 

You could just have one big terrain.
Here's how:
Click on the gear on the terrain component.
Scroll down, There is Terrain Width, Length and Height.
You can change them (If you want pretty good result try scaling them so if you double terrain height you also double all other values)
Also increase your height map resolution value the larger you create your terrain

 

Thank you so much for your reply,I could do that and am considering it if there is no known fix ,but there is a reason behind me having multiple terrains.
