The light colored area of this map are water and the darker colored areas are land. However in the legend, the colors are reversed. Something is clearly broken. I am using the most updated version of ArcGIS pro as of 6/10/2020.
This question has also been asked here:
In ArcGIS Pro version 2.5.1, the reverse ordering issue for legends still seems to be broken. The order of the numbers change but the color patches don't so the connection between a raster legend and the map is broken... reporting incorrect info.
But there has not been a response.
