Nice app… 1 issue

Very useful app with nice upgrades - I have enjoyed using it over past years. For some reason, however, now when adding a vehicle from the alphabetical drop down list, the choices for the vehicle make terminates with Nissan (no entry available for Porsche, Volkswagen, Volvo, etc).
