Modifying styling of Form Widgets issues

I just got a license for Axure yesterday and have been trying to familiarize myself with the product. I have been trying to alter the styling of the Default Form elements to suite my own styling. But when the object is not selected on the canvas it appears to be invisible. When I preview it in the browser it is visible. I can’t seem to figure out why it goes invisible when it is not selected in the Outline panel. What am I missing?

Is it all form elements or just 1 type? I was just changing styling and not experiencing that issue (on mac)
