issue with deleting a lap & mph display only in a few spots

Im very happy with the app overall but when I delete a lap from the lap list it stays deleting forever, I have to exit the app and close it. Also I would like to see my mph in more spots of the track not just the ones it chooses to show me, Im using homestead miami speedway if that is of any relevance.
