I am trying to create a statistics landing page for our county's open data site and have run into an issue with the chart card. Multiple fields are not selectable and greyed out when I try to add them as attributes within the chart, and I haven't found a reason why. I've attached an example below showing that Zoning Classification and Zoning Description cannot be added as a category attribute. This is happening with multiple layers and it doesn't seem to have anything to do with the field type, edit ability, etc.
