I have noticed that when the helpful vote is given on any issue discussion does not show the total number of helpful votes or how many given Votes are given on a single discussion.
The total number of votes should be shown on the discussion subject line like before changes it was showing.
See the below snap of this discussion having multiple helpful Votes however not showing on the top.
you can check this discussion on this link
Snap has been attached for reference
Thanks,
