The fact that a deleted template is showing up in the UI when it shouldn't is a bug. Removing it manually would be a workaround. However, if the devs don't know it is is a bug, they may not have a workaround to delete it for admins/users.

So, ask FANDOM staff if this is a bug via "Contact us". It is pretty obvious no one on these boards knows how to delete template links that should not be there in the first place.
