According to the Help Center for bronze tag badges:
You must have a total score of 100 in at least 20 non-community wiki answers to achieve this badge.
However when I look at my tags in my profile I see that for "etiquette" I have a score of 270 for 21 non-wiki answers, for "titles" I have a score of 156 for 21 non-wiki answers (+ 3 non-wiki questions) and for "time-control" I have a score of 156 for 21 non-wiki answers (+ 2 non-wiki questions) but no badges for these tags.
Furthermore if I go onto my profile and try to "Select your next badge" by clicking on the wheel next to "Next tag badge" these tags are not available in the lists presented. If I try and use the "Search for a badge" function it doesn't find any of these three tags.
It's as if these tags exist for questions but not for badges.
