Widgets not appearing in order

Hi,
Working at my site last night, I added a few widgets to a sidebar but noticed they are not appearing in order.

It seems the last widget, in order is appearing first on the WP page.
Have taken widgets off and put them back on again but it hasnt resolved the problem.

I am using Suffison as the theme but this problem just occured last night and the site has been running for a few months. I added mobile adds widget and have deleted that widget but it still hasnt resolved the problem.

Any Ideas.
