[Plugin: Facebook Page Publish] Author and Categories appearing on Facebook

I have installed your plugin today and have got my site posting to Facebook successfully. However, despite unchecking the post author and post categories in the customization section of the Settings it is still posting with this information.

The Facebook page is: http://www.facebook.com/pages/Lord-Scudamore-Academy/354712801210054

Any suggestions please?
