I am building a multi-site using Market Press

I am building a multi-site using Market Press and FrameMarket theme - using GridMarket as the child theme.

I'm having 2 problems with side bars:

1) Any sidebars I set up in the Widgets area are not showing up on my pages.

2) What IS showing up is a different side bar with items I don't want to display.

Where is the side bar controlled from and can I control it using the widgets?

I'm not new to WordPress, but I am new to deeply customizing a theme.

Thanks!
