Zwift Companion Riding Now doesn't show my bike

When I look at rider profiles during a ride, I can see the type of bike they’re riding. However, on my own profile this is blanked out. How do I change that?

As far as I know, you can’t. Zwift Companion seems to show the older bikes in the game, but not the newer ones.

Can you give me an example of older vs newer bikes? I’m currently using a Canyon Aeroad 2021, before that it was a Cannondale EVO. I had this problem with both.
