What causes this issue?

Underneath a given node of a hierarchy you must make sure that all
direct and indirect subnodes reside in the same data slice. Entity types
&V3& and &V4& are specified as nodes for the hierarchy-defining entity
type &V2&.
Entity type &V1& is at a higher level to entity type &V3& but is not at
a higher level to entity type &V4&. Therefore, you cannot use entity
type &V1& to define a data slice.
