Netscaler graphs disapeared

Since the upgrade to a professional edition of observium, we noticed that all of our netscaler graphs disappeared. There used to be a tab under health/graph called "Load Balancer" that would show a rather large amount of graphs, starting with TCP connections etc (if i recall correctly there was also a tab dedicated to SSL connections, that's the one we were actively using). I suspect that this is still being polled to the netscaler but the tab(s) just disappeared.
