There have not been any official Leopard1 deliveries for months now. We know for a fact, that there are a large number of Ukrainians officially being trained in Germany on them for what looks to be way too long and we also now that there are significantly more actually fully repaired and refurbished Leopard1s in Germany factories. There was no official delivery of Leopard1 for over four months now.
Chances are that the list is incomplete. It is meant to show a lot of weapons are being send to Ukraine and is a good tool to miss lead Russia.
