Sidebar keeps reverting to sidebar1

After upgrading to 2.7 from 2.6 every time I try and add a widget to sidebar2 or sidebar3 it reverts back to sidebar1 and adds the widget to sidebar1.

3 sidebars are registered.. I cant figure out where the problem is.. Any ideas anyone?

3 sidebars are registered.. And it worked before the upgrade

using the revolution lifestyle2 theme

Thanks
