I have a feature class of stormwater basins that is only showing one of the basins regardless of whether I choose single value or unique values in symbology. This feature class should cover a larger area, but only one basin shows up with the labels for all basins bunched inside it (Basin 4). When I select to only show, for example, basin 1, basin 4 is still the only polygon displayed. I suspect this may be a database issue but I cannot find the source of the problem. I've attached a .jpg showing the subbasins listed in the table of contents and the single basin displayed on the map with subbasin labels bunched inside.
