You don't have to use table.insert in Execute snippets, you can just `button[i] = ...`.

I think you have a flaw in the inner for cycle:

for j = 1, 6 do
    if not overridebuttons[i]:GetAttribute('statehidden') then
        buttons[j]:SetAttribute('statehidden', false)
        buttons[j]:Show()
    else
        buttons[j]:SetAttribute('statehidden', true)
        buttons[j]:Hide()
    end
end
