extra objects and export ac in blender

[willemjonathan]

does anyone know, when i created a blender file, when i export as ac i dont see added objects....so i can see the main object but not the added objects which are circular objects spheres (which i made to create lights on buildings).... in the ac file, im not much of a programmer, soi dont understand what i am doing wrong.
so if i open the ac file in the text editor i can see the different objects in it, so i can not create lights

if anyone knows, thanks version 2019.1.1 blender 2.82
