60k is and always has been the treaty exemption limit. There is talk about renegotiating it, but nobody seems to be in a hurry.
The other figures are the domestic U.S. limit that can be invoked. That limit is often changed (or the estate tax even abolished) by different administrations. This does not touch the 60k treaty limit.
Edit: Just keep on living. If the situation is too much for your nerves, it could be that DeGiro or CT are maybe better for you.
Edit2: The tax consequences are ugly though.
