Green Grid causing weird Collision Bug

In the Kite Demo, Forest and Lake map, there is a green grid that is not perfectly aligned with the ground and causes weird elevation collision. I am trying to figure out how to either delete it or align it to the map so I can use a character with the level and walk around without experiencing odd collisions.

Hello kae8947,

Could you provide me with screenshots of this issue, and does this issue occur in either 4.9.2 or within our newest release of 4.10?

Thank you,

Andrew Hurley
