I'm using Gig Calendar on a site I've built for a friend. Even though I chose "no" on the settings page when asked if I wanted a blog post to be created for each gig, it still does it. This isn't really a problem, except that for some reason, on individual blog post pages, these gigs are showing up in the "Recent Blog Posts" widget in the sidebar. You can see what I mean here:
If you click on any other page on the site you'll see that they don't show up in the widget anymore.
