Hi,
I am using ArcGIS Pro 2.9.3 and trying to symbolise an elevation .TIF file using the 'Shaded Relief' symbology in the colour blind-accessible colour scheme 'Cividis'. However when I do so, a portion of the cells in the shaded relief raster (it would appear to be those with the greatest values?) always draw in green and I can't figure out why.

I have tried amending all hillshade symbology settings (traditional/multidirectional, scaling, z scale factor etc.) but the issue still persists. There doesn't seem to be any unusual colours appearing for the affected cells when I try using any other colour schemes.
When I symbolise the same elevation .TIF using the regular 'Stretch' symbology + Cividis colour scheme, the colours draw as expected with no green cells.
I have also tried this on different elevation tiles and the same thing happens (a portion of the greatest value cells display in green).

Any advice on what is causing this and how to resolve it would be greatly appreciated, many thanks.
