User name not changing in Arcade

I changed a members name but, it did not change in the Arcade.
He is playing games, getting scores that update his stats on both names at the same time.

I had this issue way back when, fixed it... but can not remember how I fixed it or find the fix for it anywhere.

Anyone help me with this?
