I have checked that in vB 3.7.3, it has Prefix option. But when I installed in local, there is no Prefix when I want to create new post. I thought it was because of my style (Aria), but when I changed back to default style, there is also no Prefix when creating new post.
Btw I have created new prefixes in AdminCP. Just they won't show up in create new post page.
