Boeing 787-9 Livery showing as a separate aircraft

Hi there!

I just downloaded a livery for my Horizon Sim 787-9 in MSFS2024 and it’s showing as a separate aircraft and when I load it into the sim only the cockpit appears. Is this a known bug and is there any way to fix it? Other liveries have worked but don’t fall under the livery category and instead fall under variants and also have a heavy fps hit compared to the default livery.

Showing as a separate aircraft:

Many thanks!

Just an update, this issue is still happening on SU3, is it maybe something livery creators will have to change. Is there anything I can do to resolve this issue?
