What causes this issue?

When creating a hierarchy using a copy of another hierarchy, the
intervals can't overlap. When you create a hierarchy using a copy, all
of the source accounts underneath the root node are copied to the new
hierarchy. These accounts would then be present in both hierarchies
and therefore contain overlapping intervals. However, there may not be
any accounts within a relation type valid for the same day in more than
one hierarchy.
