What steps will reproduce the problem?
Whenever I rank anyone including myself it never says the name of the person, it only says [Player] every time.

I expect to say "Dell341 is now a Member", but it says "[Player] is now a Member"

What version of the product are you using?
v1.3.1

Do you have an error log of what happened?
No error, just that.
