I recently purchased the software and was excited during my trial run with being able to successfully map oyster reefs with the bottom composition module. My first real life run with the software resulted in a reasonably good depth map but my bottom composition maps appear to be totally flipped: areas that I know are hard bank oyster reefs show up as the softest bottom and areas that I know are much softer bottom show up as hard bottom. The E2 map is attached. The narrow shallow ridge in the central part of the map is a hard oyster bank (as my propeller can attest). The area NE of that is mostly fairly firm silt with occasional scattered shell as I have waded most of it.

The flipped pattern is seen on all hardness versions. Any suggestions would be much appreciated.
