The prior behavior of the macro editor, while it was broken, fit your
description. What would happen is it would effectively wipe the memory in
the command station. What I don't recall is which version JMRI was the first
one with the fix. So that is the thing to confirm, when was it fixed and
which version you had. I think you said 4.12.
