Cannot See Contact Widget

I have a theme I purchased and have tried asking there with no luck, but I am trying to change the contact information and map on the contact page of my theme but CANNOT find the widget. Even though the contact page exists on the left admin pane, I don’t see any widgets except for my home page widgets inside of the widgets! How do I find the widget so I may change, for example, the google map in the code? How do I find any widgets on the residual pages, like say, there’s an “Our Team” page I cannot even find that is published too.

I’m a newbie..
Here’s the page,
