DTM & point cloud all BLUE

I ran Elevation grid on the point cloud plus some pond area features. COLOR BY LIDAR ELEVATION - All Lidar went blue.
Hi have checked for any high noise.
Even a PC that was not selected for gridding is blue when active.
This must be something really obvious I think.
Thanks
