Professional WordPress Plugins and Services. wpDiscuz, WooDiscuz, Advanced Post Pagination
This is not a bag, it's the working logic of this add-on.
The wpDiscuz Advanced Likers add-on detects users by its ID, and if the user comments without being logged in, it detects this user as a guest and doesn't count the account role so doesn't display commenter badges.
We'll take it into consideration to change this logic in future releases.
