Hey there! We're having a bit of a problem:
We're symbolizing by unique values and a couple of symbols weren't showing up in the legend.
Then we noticed that the feature count in the symbology pane says zero for these same values.
So, I had a mini-heart attack and checked to make sure the features are in fact in the SDE feature class.
They're all in there.
Any ideas why the count isn't showing up?
