Ad Manager displays insertion code in RSS

Plugin page: http://ww.wp.xz.cn/extend/plugins/adsense-manager/

Not sure what I’m doing wrong but all of my rss feeds have the insertion code for this plug in visible.

eg: http://feeds.feedburner.com/petsnakes

If you go there at the beginning of each excerpt you’ll see “[ad#mainbody]”

Anyone have any ideas?

This has been happening since 2.5 that I’m aware of but after upgrading to 2.7 decided I’d like to try and fix it.
