Partial is rendered twice in ActiveAdmin

My partial is being rendered twice: at the top of the page and at the place where it's supposed to. Apparently, this only happens when I have ActiveAdmin-specific code (table_for).

Any help is greatly appreciated. Below are some code snippets I'm using.

In my active admin file:

panel "Children - SubProcesses" do
    text_node link_to "New", new_admin_sub_process_node_path(:parent_id => process_node.id)
    div render :partial => "/admin/process_nodes/child_list", :locals => { :parent => process_node }
end

In _child_list.html.erb file

<%=
unless parent.children.empty?
table_for parent.children do 
    column :id
    column :name
    column "Actions" do |child_node|
            text_node link_to "View", admin_process_node_path(child_node)
            text_node " "
            text_node link_to "Edit", edit_admin_process_node_path(child_node)
            text_node " "
            text_node link_to "Delete", admin_process_node_path(child_node),  :method => :delete, :confirm => "Delete?"
    end
end
end
%>
