I have a map of the US where I grouped counties into 250 county groups in a feature layer. I am trying to change the colors of each county group. To do this I click "Change Style" then "Select a drawing style: Types (Unique symbols)" for the layer. I get an alphabetical list of the unique county groups that I can edit. The problem is that I can only change the color of the first 200 groups. The 50 groups at the end of the list are all grouped together as "Other". I click on the "Ungroup" button, and nothing happens. How can I ungroup the county groups in "Other" to change their colors?
I was able to get around this glitch by moving all of the values out of the group then saving the map - without attempting to navigate out of the "Select a drawing style" panel in order to click "Done".
