You're absolutely right. I changed it. There was only a single profile affected.
There's something else strange about the profile that I can't figure out: it looks like a floating [[Category:]] tag, in the profile view. I tried to delete it, but can't find it. I'm also not sure that the profile needs both a
category template, and a
[[Category: Indigenous Peoples of Mexico]]
category. I would guess the 'Indigenous Peoples' category is a higher level category that should be deleted off the profile.
