Cannot find or edit sidebars

I am using Customizr. site is PDServices.com
I need to change information in my right sidebars. I have a custom sidebar for almost every page.
When I go to Appearance, Widgets, I can see all of my sidebars listed on the right half of my screen but when I move into that part of the screen everything disappears.
there is a button on the left side of my screen that says Manage in Customizr but when I click that, all that is available is the regular right sidebar. I needed to make a change to that also, and it looks like I did but on my actual website, the change did not take effect.
So #1 is where can I edit my custom sidebars and #2, how do I edit the right sidebar?
Thank you.
