Forums username question

I do have a question though if you have any idea or able to answer it about my username. I changed it last week before the beta and is showing my new username on my EA profile in BF6 and the email I got with my BF6 weekend 1 stats but it's still showing up in these forums as my old username that I made many years ago will it change here in the forums also? Or how do I go about getting my new username to display in these forums? Thanks
