What is broken and how can it be fixed
When you hover over your username and click a badge it will open up the whole list of your badges. You only have 3 and you're new here so you won't see what regulars see. But in there we see every badge of all levels of community participation. ie. top 50%, top 25% etc.
The error is that it should only show the one valid earned badge.
What is not an error is that we also get notifications of the level of community participation badge which is correct. And we see the amount of earned reward in our rewards area which is also correct.
So the only thing to fix, which doesn't exactly really matter, is the showing of all the error badges.
