Tunes not sharing on certain cars.

Have an original Xbox One.

Have tried to share tunes on the following cars -

2010 Renault Clio RS
1992 Alfa Romeo Milano
1966 Ford Lotus Cortina

On each occasion while trying to share the tune, the game just crashes to the Xbox home screen.

This is kinda a big deal for me as i really enjoy the tuning part of the game.
