Option results not showing in comments

The rating can enable in the comment by checking the next checkbox of content type checkbox.
Follow the below steps -
Structure -> Rate widgets -> Add/Edit widget -> Find entity section and check for comments for related content type.

If still not getting rating option in comment section then error may be in console or Drupal log.
It working for me and attaching screenshot for confirmation.

Thanks for your comment.
However, my problem is not enabling the fivestar widget for comments. I can well enable it. But, while for articles it displays the average points after all votes, in comments, this value always remains at 0.0, no matter matter how many votes have been cast. See pics attached.

Can you please give exact steps to reproduce this issue? Also some more information on your setup (which entities, how are comments added etc.)? As helpful pictures are in other cases, this one sentence and the two small pictures are insufficient to reproduce this issue.
