Footer sidebar is top now

Hi

Please advice. I think it is the custom sidebar that caused this.
My widgets in footer sidebar has suddenly appear in top of header now on all pages.

I fixed it on the homepage where I saw the widgets has moved from footer into main sidebar. Then I unchecked that this sidebar can be changed.
How can I fix so all pages are back to normal??

I think this happend during upfront activation.
