Get Missing Registration to Appear

Is there any way to get registrations to show on planes where they are missing? (Latest Beta)

For the A2A Comanche, for example, the stock registrations (or custom ones) show on the side of the aircraft, but on some repaints with dynamic registrations they won’t display at all.

Is there a trick to force the registration to display (even if it’s a fixed vs. dynamic registration)?

Thanks…
