I have just done the following:
- set number of copper layers to 8
- placed a few buried vias between In2.Cu (3rd layer from the top) and
In5.Cu (3rd layer from the bottom)

Now when I decrease the number of Cu layers to 4, the vias remain but
have the target layer undefined as In5.Cu does not exist anymore. Once I
reduce the number of Cu layers to 2, they disappear. Restoring the
original number of layers brings them back.

Is that what you see as well? As far as I understand, the items are not
deleted as they are restored once the required layers are available. How
to trigger the issues you describe?
