Wrong postname in list

Hi,

This plugins works great. Except one thing:

When I activate the widget and fill in the the custom field name, the widget shows wrong postnames. See screenshot behind the link

It shows the excact database entries like:
> a:1:{i:0;s:4:”Open”;}

But it only has to show:
> Open

Do you know how I can solve this?
