Owned cars missing in online and offline modes

After transferring data from one PS5 to another most cars in my garage on both online and offline modes has vanished. A second PS5 profile which was also transferred to the new PS5 has all the previously owned cars in both modes

Screenshot of what's left attached. I had won and bought numerous cars as I progressed.

Any ideas what went wrong or how retrieve this? There is no way I'm restarting the grind.
