I created rasters with using zonal statistics to calculate the maximum value in each polygon
When I am setting symbolization by Unique values in Pro (2.4) I see some artefacts (see small dark, grey and blue areas in the middle). I don`t see these colours in a legend of this layer.

I don`t have such a thing in Desktop.

It looks like a bug. Do you have an idea what could happen?
