The page text specifically states "all versions" of Fullmetal Alchemist, not a single version, so pointing to a single version instead of the disambiguation page is not desired on this page.
If we wanted to blindly replace all of the links, we would have run a bot job.
This isn't the first time that I've mentioned this to you. MOD: Please be more careful when you replace disambiguation links.
