Why are my attribute tables full of null values when making filled contours?

Hello,

I am a novice ArcGIS (v10.6) user working with a large aerial LiDAR dataset. I am working with an xyz file and have extracted terrain height and tree heights out into my workspace.  I then used focal statistics to make a courser representation of the data and used contour tool build contours and labeled them.  I really want to make these contours filled. I downloaded two toolboxes to make these contours filled but when I run either filled contour tool on my post-focal point tool all my contour attributes are nulls so I cannot get my result.  When I run the tool on my raw terrain data I get contours but still the attributes are all nulls.  I have all the extensions turned on. What I am doing wrong?

Thanks,

Andre
