TestStand fails to load dynamic dispath vi that inherits from an interface

Hello everyone, 

 

I have a base class that inherits from an interface and a child class that inherits from base class. 

When I try to use a method from the interface with the base class or child class I get error -17600, failed to load vi. The namespace shows that I selected the class implementation but the original namespace remains to point to the interface. 

 

I know the inheritance structure so I can select the inheritance namespace explicitly but for someone else working on this program it might be confusing. 

Is this intended behavior or a bug with the introduction of interfaces?
