I think you're referring to your Wikia profile, not your MSM wiki profile -- they're not the same. If you go to your "Profile" page, and mouse over the area that includes those links, a small "Edit" labe should appear in the upper right of that area. If you click on that, you can edit your Wikia profile. Delete the contents of the Twitter and Facebook fields, and those items should disappear from your profile when you save your changes.
