Was Doing Fine Then All Sudden Home Page Changes On It's Own

I spent all day working on my site, saved everything and next day I come back to my site and the Home Page switched on it’s own to a page call “Umbrella Design”. Now there are addition components added to that page I didn’t add. I try to remove them but instead of removing it adds more content and text boxes. This is the weirdest thing I’ve every seen.

Can you help me fix this problem.
Here is link to my test site.
