Why are there sections that do not fit on my screen, such as when the track names do not display on the Card Menu Selection?

If this occurs on the Card Menu Selection screen, try reloading the page and then the names of the tracks on the left should load. Please try to increase the screen resolution on your computer to a higher setting (min. 1075 width). That will allow more elements to fit on the page. You can still adjust the actuall Past Performances to any size you wish by using the Settings menu.
