Sounds like you have no used the 'VideoScale' function on the LUT before exporting from LightSpace for use in the eeColor LUT Box.eeColor LUT Box LUT Format
Depending on the display and source in use (data range, or TV level) the eeColor LUT Box may requires LUTs in a particular data range.
For TV Levels, after the calibration LUT has been generated via LightSpace CMS in the normal way, use the 'Edit/LUT Manipulation/VideoScale' function to format the LUT data correctly.
For data range display workflows the re-scale will not be needed.
