UMG: Invisible buttons in editor!

So I am creating a start screen for my game. In content browser I created a Widget Blueprint -> Root-> Border -> Canvas Panel -> Vertical Box -> Button -> Text Block

I set up a blueprint to attach the widget on the camera OnStart however while editing the GUI the buttons are INVISIBLE!!! This is making it extremely hard to edit the fonts color size and style.

However when I play the map it works perfectly fine. Is there a way I can make the buttons visible in the editor?!

Please and thank you!

Could it perhaps be the ZOrder?
