Not on Colors being displayed on the charts

I created a geospatial scatter chart using MongoDB and some data is being displayed on the map. However, not all the colors on the side of the map are reflected on the chart itself. What could be the reason for this? Here is the clientID of the chart and a screenshot for further clarity

clientID: 64640fa7-a657-4630-8ed3-58b1711c6d5e
