Added property "displayName" to bottlenecks. Before displayed, bottlenecks ordered by country are now checked for doubles per country. In case a double is found the displayName is enriched with the bottleneck_id. Otherwise the displayName is equal to "name" or "objnam". Example: const testList = [ { properties: { responsible_country: "AT", name: "Bananas", bottleneck_id: "BN1" } }, { properties: { responsible_country: "DE", name: "Bananas", bottleneck_id: "BN2" } }, { properties: { responsible_country: "DE", name: "Bananas", bottleneck_id: "BN3" } } ]; is rendered to: AT Bananas DE Bananas / BN2 Bananas / BN3
