Object doesn't show : loaded or not loaded ?

Hello,

I am meeting an important issue.

My question is very simple : what does this mean ?

Basically, I load a scene from another scene using LoadSceneAsync(MY_SCENE);

But when the scene is loaded and appears, some objects are invisible. When I check the inspector to see what is going on, I see the previous screen :

• My Layer is correct

• The MeshRenderer is active

• The gameObject is active

• Structure_FloorA is loaded (I know because it's visible somewhere else in the scene)

The only problem is the cube box on the top left corner that tells me the ??? (not sure what this icon represents) is disabled.

If I disable-enable the gameObject in the inspector, the object appears.

I am using 5.5.0f3

Does someone know what I should do ?

Thank you for your help

EDIT : apparently, this bug is specific to editor mode. This fact reduce the emergency of finding a fix, but it's still make some tests in editor mode very complicated to perform, bescause code is executed in the Awake function of the disabled objects.
