Global Mapper v25.0

Changing the shader color values has no effect

Hello all, 
I have Lidar data loaded into Globalmapper and I'm trying to export as a black/white gradient heightmap TIFF (raster image). I understand to do this I must disable hill shading (which I've done) and also set the shader to gradient coloring. For some reason, even after all of that.. the image still displays as a multi-color map. I've set the the gradient low color to black, gradient high color to white.. I've even made a custom shader at the bottom of that options page but nothing changes after clicking "Apply". 

Any ideas? Thanks in advance!
