Sprint Race events not displaying correctly

Something similar but not exactly the same has just happened to me on Xbox in Grand Prix mode 25%. Done the Austrian weekend fine but then went to France and instead of just qualifying and race. There was a sprint race. I just clicked advance and sure enough there was a 13 lap sprint race which is a full 25% race with no pit stop strategy. I retired after the first corner, then the results pop up, and full race points were giving out but no pit stops made. Next race is Hungary, and it is normal qualifying and race. But something is definitely not working properly in the sprint races. I will upload a few pics later.
