Featured contents data wiped.. why??

I set up 4 columns of Featured contents each comprising:- Image Link URL Title Content. Everything was fine. I swtiched from one link to another, to the Home page and other pages. There was no doubt the Featured Content was saved, and working as expected. I then added the url for the facebook page and saved. On returning to the Home page, all the Featured Content data has disappeared, except the Title. ( no image, no url link, no content) I'm not a newbie and know my way around different WP themes. To lose saved data is very worrying and could be a disaster if a website using Adventurous is published, and then begins to crumble from within. Has anyone had this problem? Thanks in advance Marek
