UI pivot doesn't work?

Hello, is it just me or is the pivot not working sometimes?
Sometimes its just kinda faded out making it look like that its disabled.
It works when i change it in the inspector, but i cant drag on it in the scene view and its also not positioned in the right place.

You are currently in center mode. Click the button that says “center” to the right of the rect tool, and you will switch to pivot mode. That will shift your pivot to its proper place. See this page for details: Unity - Manual: Basic Layout
