unity 5 3. Cant disable canvas game objects / grey scripts

Hello. I have some problems with unity 5 3.
1 I cant disable some game objects under the canvas, it just does not work. I tried in editor, tried in sctipt (gameObject.SetActive(false) ; nothing. So i cant disable my GUI / menu elements.
2 all scripts attached to game objects are grey, i dont know what it is, just asking.
They look like this:

all of them.

 

If you add OnEnable or OnDisable to your script, it will show you the toggle to activate and deactivate the script in the editor.

 

Yes, but i need to disable gameobject not script.

 

Can you show a screenshot showing the hierarchy and the inspector with a misbehaving game object selected?

 

Yes.

Here i am clicking the checkmark and nothing happens. gameObject.SetActive(false) also does not help.

 

It looks to me as if you are having a script that automatically activates the game objects. Do you use [ExecuteInEditMode] in your scripts?

 

No I have no edit mode scipts. And it is not the only problematic object. And not only on this scene. I cant recreate it but i noticed that it happens only on canvases.

Edit:
So I created new Canvas with same settings and moved all gameobjects to the new one, and now problem solved. Seems like a bug that i cant recreate, all i can remember what ive done unusual for me is draging this canvas(broken) from the other scene trough new multiscene editing tool.

Scrits are still grey.

 

Does this also happen when you create a canvas in an empty scene and add e.g. the HUD as a child in there?

I don't have any experience with multi scene editing. So I wouldn't be surprised if it is related in any way.
