Each practice added to your project needs a geometry to delineate the practice area and extent. These geometries display on a map on the project summary page. If you have more than four practices, however, only the first four practices that you create will display on the project level map.
Do not worry, this is an expected behavior. The funding program manager will still be able to review and access all practice geometries. Furthermore, the metrics associated with all practices, not just those four displaying on the project summary map, will appear rolled up on the project summary page.
