Trying to redeem a product code

I have been trying to redeem a product code for Battlefield 6 that I got for Christmas and everywhere I try to redeem the code shows it has been redeemed. I entered the code in my account management and it shows this. 

SANTIAGO - STANDARD EDITION Long Description Placeholder Text. The submissions process has not yet been completed so this content does not yet have all the final assets. Before you write a bug for missing or incorrect assets or strings, please confirm the timeline for when submissions for metadata is supposed to be completed.

How do i get this to work?
