text: Hm, so I'm not seeing much that we would need to fix within OpenStreetMap.
  
  From a quick look, Circuit looks to be using Google Maps data? But Google also seems to show the roundabout shape correctly. Sygic can use several sources, from https://wego.here.com/?map=51.02588,-114.08908,19,normal it looks like Navteq/HERE might not have this completely mapped (maybe missing the no-U-turn in the teardrop?) - but that's not OSM. In any event, I'm not sure it's something we in OSM can fix. Sorry!
