Yes, and if this does not help, I believe TBC < 3.4 had a bug that when you switch models, then the query view of the SPARQL view is not updated automatically. As a result, resources may appear undefined even though they are indeed defined for the (newly active) model. This problem has been fixed for 3.4 though.
