ok, I've tried to solve this on my own for a while, and finally after I ask for help, I finally got closer to the answer!
In: Tracker Properties > Display > I chose the option 'Configured'
Now the wiki page with TrackerList displays the template, but without any data.
I've tried also checking the box 'Use Form Classes' but did not change anything.
I also tried adding the 'Input Form Classes' (both options 'form-horizontal' or 'col-md-9'), nothing changed.
So the last step I can't figure out (yet) would be how to get the wiki page template to be filled in with data.
