Export Simulink to Web needs to be repeated many times to display all levels of the model

I want to export to Web a Simulink model having many levels (layers when navigating down subsystems) with library links. I found out that running only once only gives a couple of layers, so I have to run for 7-8 times to be able to navigate in the whole model. This is valid for both the GUI export or command line export via:

    WebView = slwebview(modelName,'SearchScope','All','LookUnderMasks','all','FollowModelReference','on','FollowLinks','on','ViewFile',false);

It is time consuming to do this and I have to do this for about 10 systems. Any idea how to fix this?
