Xbox - unable to look under hood of cars

Apologies if this has been posted before, I did look but couldn’t find a similar issue.

The option to open the hood to view the engine has disappeared for a few of my cars. It seemed to happen after downloading a tune for it. Previous to this, I was able to open the hood.

For example, when I first bought the 2018 Mustang GT I could view under the hood. Now I am unable to do so in Forzavista. The “button” that appeared on-screen is now gone.

Any help would be greatly appreciated!
