Canvas renders in play the wrong size

[Light]

I have an options scene here, when I look at it in the unity editor, or click play, in unity it fills the screen correctly like this >>

However, when I build the game and run it, the same options menu appears like this>>

I am using the UI Canvas with the Scene overlay option. I have this setup for the start menu and some other scenes that are all working correctly, Its just this options menu and the end game credits scene that are rendering small like this. I’m sure I have made a simple mistake or clicked the wrong option somewhere. Any ideas? I’m so close to being finished with this game!!

the screen is scaled to the size always you have and you can put all the images seamlessly scale the screen.
