So I had recently got the ‘Top 10%’ badge and wanted to make it my title right away. However, I found that there was no option to select title when I tried to do that.
The ‘Top 10%’ option was visible to me only when I went to my profile and assign it as my title from Badges. However I couldn’t assign it to myself when I clicked the badge (the page where one can see others who have received the badge) and tried to assign it from there.
