[copy of answer from below] The Wikipedia database doesn't differentiate links which appear in the main article versus in the sources or categories sections. It's possible one of the intermediate links is in there. You sometimes need to do a CTRL+f in "View Source" to find the link. Also, the latest Wikipedia dump is from February 2nd, so it's possible the link has been deleted since that date. I'll regenerate my database when the new dump lands in early March.
