Accessing Search Templates in Smart View

Hi,

I'm noticing inconsistent behaviour around Advanced searches that are saved as search forms. My understanding is these (as opposed to saving search query) are to be accessible to Smart view search, i.e. so you can in classic view, save an advanced search page (i.e. one with metadata) and access it from the search icon in Smart View.

I'm finding that such a saved search form is only sometimes accessible, and sometimes restarting both browser and Content Server service will bring it about, but sometimes only after several restarts. What exactly is the expected behaviour of a saved search form (Search Template node) in classic view as to when it is available to smart UI?
