Unused Body Styles for old Pessima

Hello, I found unused body styles for old Ibishu Pessima like Hatch E, Cargo FA, some UTE body style but they are unusable. My question is: Is there plans for some next update or it is because of mods??

 

These body styles are part of a mod.

 

But I can not find any mods to use it.

Oh! I found it now it is bug of mod that adds unfinished body styles.
