You can solve this problem by simply moving the charts up or down in the «Maps» panel or switching them ON or OFF. On the picture on the right, we show the chart from Switzerland on top of the one from France. So, if we move it below, the latter will show on top of the former. This is shown on the picture above.
Troubleshooting
- My installed maps are not showing
- Check that they're enabled under Map Options - Maps. If they are and you are still not seeing them, make sure to place them at the top of the list. They might be hidden behind another chart.
