Ontology option seem to be lagging behind?

If you switch between the ontology filters, it doesn't always update the cytoscape graph, which confuses the user on whether what they're seeing is correct.

with shared nodes 'on' and with a graph for biological_process if I click either of the
other two ontologies the graph doesn't change but in fact I think there should
be no graph, so this is potentially misleading. Again, greying out those labels that
have no results would be good
