Ok, last patch fixed the name bug that displayed the shuttle name in the shield UI instead of the starship's name... But it broke the name on the ship's decal. While it was working correctly before the patch, it now shows the shuttle name and registration number.
Actually the registration number in the screenshot below looks the same because both ships had the same number. After changing the number in the shuttle, the name changed in the ship's decal as well
