Vehicle settings not accessible for non-saved vehicles

I often road trip with bike racks and in the winter with non-original tires making using the reference consumption feature effectively mandatory. I meticulously change this in the beginning of a trip to be accurate.

This trip that feature seems gone and all my stops have been off wildly - sometimes up to 30% and multiple times meaning I’m going 20mph below the speed limit on the last 30 miles and ALSO arriving sub zero.

Did you really make your app worse????? Bring back reference consumption please!! It really has become unusable for me now.
