Things get a little weird when you have multiple of the same platform linked to your EA account. I recommend that you reach out to our live support team, they can take a look at this for you, and help you unlink one of those:
live chat and e-mail options are unavailable, I have tried several times. I have had an EA account for 10 years and I am disappointed with their support…
@locc093 Sometimes using the EA Help site while signed out of your account or using Incognito mode makes the option appear - have you given that a try yet?
