Unable to add widget to Upfront Theme

I am trying to edit the Upfront Theme Fixer. What I am doing is trying to add a widget to a region. I am able to add it to the region but I am unable to access the settings page for the widget. The widget area in the region will not allow me to click on the padding or settings icon.

To replicate you would add a widget to a region then try to actually select the widget to use. It won't allow you to access that in order to set which widget it should be.
