I can replicate this bug using an International Transtar that is already equipped with a snorkel. I uninstalled then sold the upgrade. It then showed the upgrade as locked out with a broken string reference. I can access other options on this page such as engine or frame options, but as soon as I change to go either to the left or right page, the menu goes black and you are unable to exit the customization menu. A force close of the application is required. PTS level is 29 just for reference.
When attempting to change to next page, menu goes blank
