Is it correct that the response on a slider, I specifically set a response, does not show in the reports?

And can only be seen in the csv file report? 
Oops, I thought it could be seen, but it cannot be seen. Giving an answer to a slider at my side, does not give any answer... 

Also my test in the demo-section of the surveys in corejoomla over here

https://demo.corejoomla.com/surveys.html?view=report&id=11&layout=response&rid=2724

does not show the numbered answer that I selected in the slider. 

cheers,
