Ok i added a taxonomy reference field to a field collection and a textfield. The vocabulary has some terms with parents

-Dog
--olddog
--newdopg

I chose a parent and a child. Somehow field collection will not display the two terms together, instead it treats it as if there were two data rows, meaning i get two rows

value textfield, term parent
value texfield, termchild

what i would expect is

value texfield, term parent, term child
