Ue4 landscape clipping through spline mesh?

Hello I’ve been trying to make a road, on my map for quite a while and I keep coming up with the same error, that being that the landscape mesh seems to keep going through the roads. I don’t use unreal a lot so any help will be appreciated!

I have the same issue, i do think i know How to solve it but i am not sure. Will comeback if I have any updates
