Steps to create problem.
Create a flow graph with an input and then use it somewhere in the program as a super unit.
Go back to the super unit graph, and to the input, add a new Value Input. (new input is propagated the super unit instance).
Check Has Default Value (which defaults to 0) (again new input is propagated to the super unit instance with the default value of 0)
But change that default value in the graph and that change is not propagated to the super unit instance. It remains 0. However, if you change the default value, then uncheck the Has Default Value box, then recheck the box, the value you set it to remains and that value is then propagated to the super unit instance.
