Positioning Label with NGUI

I have a little problem, and i don’t know how to solve it.
I’m using ngui to create a label for the score, i’ve positioned it perfectly, and when i hit play it works 9/10 times.
The other one time, the label’s position changes randomly, i can’t find why.
I thought i could build the project and run it to see what happens: The label’s position changed.

the first picture is what appears when i hit play (what should happen)
the second is what i have when i build and run it

does anyone have any idea how to fix it ?

For those who might have the same problem, it’s simple, just Anchor the Label :slight_smile:
