Account Migration with Twitch Not Working

So I've been trying to get the streaming with twitch to work with my minecraft game. Every time I try to do the migration I get an error from the site where I do this from. Saying how I can only own one account at this time. I'm pretty sure I already migrated my account but the game itself keeps telling me to migrate it. I already linked my twitch account to my Minecraft but I don't know what it's doing or what to do with it now.
