Cannot see goals from subordinate business units

I have:

- a BusinesUnit1 with a child BusinessUnit1.BusinessUnitChild1

- a user in BusinesUnit1 and another in child BusinessUnit1.BusinessUnitChild1

- an objetive in in BusinesUnit1 and another in child BusinessUnit1.BusinessUnitChild1

- both users can read objetives to subordinated business unit (3 quarters of the pie)

Why the user from BusinessUnit1 cannot see objetive in child BusinessUnit1.BusinessUnitChild1?

Thanks
