Button Disappears in Build?

I have a static button on my UI that appears onscreen when the game is run in the editor, but when a build is made and the game is played in standalone, the button is gone (offscreen?).

The button is parented to a canvas. There are other static buttons parented to the canvas and they show up fine in both the editor and standalone.

Any idea why the button disappears?

Thanks!

Got this sorted.

An older version of the scene was present in the build settings and this scene did not contain the new buttons.

When I put the most current scene into the build settings, the buttons were properly displayed in the build.
