So the actual transactions took place immediately before and just after handover to a new general secretary. Later, under the new secretary, a correct return was filed (who thought to do that? why did they decide it was best?). I'm going to infer that the newcomer faced a big pile of things to do, as you often do when someone knows they're leaving and doesn't pay as much attention as usual, and fixed the problem when they found out, possibly after some righteous swearing.
