Ted this may not be a bug but part of the new layout. When you are in a race there used to be an ability to get to further races at the same track by hitting the buttons at the bottom.
Now in the new version, from what I see you have to go to the card summary at the top and then to the race. Not as efficient as before. When flying through the races exporting info, this is an inconvenient extra step.
However I am loving the ability to import results and scratches etc. This saves a lot of work and makes the update worth the wait.
