Beta 3 Bug: Terrain Painter detail distance value not updating consistently

if you load a level and go into the terrain painter and then adjust the values of a material. I can reproduce this every time with the detail distance value. It will let you change it Once then you hit select so close to the terrain material editor. It will then update the detail in the view. But if you go and try to adjust it again it will not update. You will have to save and then close the editor and open it back up. "This is due to the crash on new level load bug".

If you open the editor and the same level you can adjust the value again and it will update for the first adjustment but all later adjustments fail. I have tried this on 4 machines and they all produce the exact same results.

I have been using Warrior Camp for this test BTW.
