Segment & has other attributes in predecessor

What causes this issue?

Segment &v1& has several attributes in the predecessor (mandatory
segment, parent segment).
A segment that is also in the predecessor must, however, have the same
attributes as in the predecessor. Otherwise, compatibility would not be
guaranteed.
