[Plugin: Yet Another Related Posts Plugin] Related Posts *always* in RSS feeds

Hi

I’ve just installed YARPP and it works great. My problem is that I can’t seem to switch “related posts” off in the rss feeds. I uncheck the “Display options in RSS feeds: Display related posts in feeds?” and even put zero as the number of related posts to display, but it takes no notice. This happens whether I have related posts on the website or not.

Any ideas?
