Unified search click statistics without Track()

Hi,

I´m trying to send click statistics back to Find using ISearchService method TrackClick(string query, string hitId, string trackId) on Unified search result without using Track(). But I don't get any registrations of hits under statistics in the Find CMS view.

It seems to work fine if I add Track() to the request and remove all the query parameters added to the URL for the hit so it only uses my custom TrackClick() implementation. 

Is something activated in statistics when using track()?

I have been looking at this guide https://world.episerver.com/blogs/Henrik-Fransas/Dates/2015/2/how-to-do-custom-query-and-click-tracking-with-episerver-find/ when setting up the code and it is linked to from the dev. docs.

The code doesn't indicate any errors when executing.
