Hi CC Lindsey,
Could you capture a screenshot for the map and the map list in worksheet? When we create a map chart, it will create two types of map according to the value. One is category map which display different colors for different value. The other is value map which display graduated color. After you select data range, click Insert>Recommended Charts>see if you can find two kinds of maps. If yes, select the category map.
Best regards,
Tim
