Editor drawing UI elements correctly but WebGL and PC not drawing them as expected

Hi,
I am using a few Buttons, a Label and Textfield in my opening scene. In the editor they render the buttons exactly as I expect. All scenes have the same buttons throughout. All the other scenes' buttons work like the editor version and look rather nice. However, the opening scene does not draw the buttons, label and textfield as expected. It barely draws them at all.
Here are some screenshots and my code to see if anyone can help me:
Script

Build

Editor


I have been searching and I cannot find a similar issue. It is so frustrating because all that appears on the screen initially is "Please enter your name below" and no box to type the name. You only get a cursor appearing once you click the space directly below the Labels text. Not intuitive for a user.

As I said, this only occurs on the first scene of the game. All other scenes work exactly the same in the editor as they do in the final build.

All help appreciated, Brent

 

Have I posted this in the wrong forum?

 

Hi, check the canvas scaler property

cheers

 

What exactly do you want me to check about it and why would that solve the issue I'm having?

 

What attribute are your using for the UI scale mode

 

This is not to do with scale. The GUI items do not appear only in the first scene. I appreciate you trying to answer but scale is not the issue.
