Label and data missing from map

I am using vcharts 2.9.21 on Joomla. I've created a chart of type map. I manually filled in the countries and values in the backend, but some of the countries are not showing their labels or countries. (See attachment). Please help. You can see the map live at the bottom of learn-dev.afrinic.net/events
