When trying to display a data set (from Collector) with symbology varied by multiple attributes, I have encountered a frustrating problem. Approximately 1/3rd of all my points incorrectly display under the "all other values" item. At first I assumed this was a formatting error, but when I tried to manually correct some of the points in the attribute table, nothing changed in the symbology. I am new to Collector, so possibly I did something wrong setting up the fields there? But most of the points display correctly! Any ideas are appreciated, I am on deadline and tearing my hair out.
The picture here should show what I'm talking about. The selected point should display as "POTR," but instead is "all other values."
