RSS Category Feed Only Shows 5 Items

I have enabled category RSS feeds and have set the number of items to 20. No matter what I do, it only shows 5 items in the feed.

You can see the feed at:

The feed on the left is patches and it’s only shows 5 and it comes from a category with over 30 items in it.

The feed below the patches on the left is the whole store rss feed and it works just fine.

Why are the category feeds only showing 5 products and how do I fix this?

I appreciate your time in trying to assist me,

Nobody? Bueller? Is this normal behavior? I submitted a credit funded help request… when I get an answer, I'll post it here so maybe someone else will be helped.
