    this is a port rom, so it is likely that when you connect the device to the PC or via bluetooth it shows a different model, it is normal since it is a hybrid between the original rom and the port
    the rom it on beta state so please report any problem

    I'm not a developer, I only have some general knowledge, and experience porting rom, but I don't even have Linux installed

    I leave the link of the original rom of the g360h that has almost the same hardware as the tab e, all the recognition for the creators of it
