I linked the wrong account and now it won't let me link another

So I have a couple of epic accounts for Rocket League, and I have already linked (ABowlofBroccoli) to my tracker account of the same name. Well I accidentally did the same for this account by forgetting to put in different login credentials.

Now when I try to unlink and link my other account (Triforce 94) to this one, all it does is force me to link to the first account.

Any help is appreciated
