Landscape max draw distance change not working

Hi there !
I have a problem with my landscape… I did a while ago a change in max draw distance and now I cannot make it back to initial settings…like no “culling” …I don’t know why is not working to reset this and have no “Culling” anymore…Can someone help me please? (btw: I did that trick with 0 and than the requested value in the max draw distance but it doesn’t work). Also only in game mode view the landscape is “culling” by tile.

For anyone else that have encountered this situation…this is the solution:
Resample, apply, restart ! Worked for me
