Question Unity docs: Editing properties

Hello!
There is a doc on "Editing properties" that I have an issue with.
At the "Numeric field expressions" part there is
1. an example of using a linear interpolation L(-6,6) for X coordinate of multiple objects, which works fine for me.
2. an example of using a randomizer R(-2, 2) for Z coordinate of multiple objects, which also works fine
3. an example of a "multiple" division /=3 for Z coordinate of multiple objects with different Z value. Which doesn't work for me.
I didn't find any open issues about that and nothing in changelog too. Does anybody know anything about it?

 

My bad, works on an empty project. So the problem is NGUI, which has a custom editor for Transform.
