Layout Option previews but doesn't save

I'm editing a page to change the layout. I look in the "Catchresponsive Options" panel at the bottom of the Edit screen, selecting "No Sidebar (Content Width)" in the "Layout Options" tab. When I click the "Preview Changes" button, a preview pops up with the new layout. Looks great! When I click the "Update" button, WordPress shows its little spinner, but then the screen reloads and the option has been set back to "Default"..? I've checked the published page but it hasn't switched to the new "No Sidebar (Content Width)" style, and the revision history doesn't show anything has changed. I'm using v1.1 of Catch Responsive with WordPress 4.1.1, in IE10.
