I've done some investigation.
Each section of the camera_facing.ini must have only one mesh (it's not possible to trunkate the mesh names or use "?").
If you have 10 grandstands you must have 10 separated section inside camera_facing.ini.
When I was investigating I came across with the following issue.
I tried with one big and small grandstands and the crowd work fine.
Then with 2 of each one and was fine.
And so on, untill I put 5 of a kind and the names of the last ones meshes were different from what I expected.
With TD they were name as I expected (gg_building_grandstand_01_a-2
_4, gg_building_grandstand_01_g
_4)

But after creating the KN5 in TD, extract the FBX and creating the KN5 in KsEditor, the
_4 were truncated from the mesh names

Then I tried with 6 and all the mesh names were in sequence again.
I've also tried adding (at the end and between grandstands sections of the TD model.ini) also a different objest (a brake marker) and the crowd was still there
