@paulkentI found the issue. On your profile you registered a Personal Car. When adding this car to your profile you set it up as Vehicle Type Regulated Rate. However, your site administrator entered XBX Casual Driver 45 on your back end profile. So, there is mismatch between the these two things causing the red exception. You need to log into SAP Concur, click Profile in the upper right. Select Profile Settings. The on the left side of the screen, click Personal Car. Here you can update the Vehicle Type. I provided a couple screenshots below.
