From you saying you bought the game twice, I'm gonna guess you had the collectors edition on last gen and upgraded? If this is the case then unfortunately you'd need to purchase the collectors edition upgrade for current gen to use your emote. The disc contains the Base game and has no bearing on any additional content.
Sounds like you've been screwed by how these things work unfortunately. I'm guessing seeing as how they don't work when upgrading is the whole 'only work on the console redeemed' thing rings true between consoles of the same gen. Feel bad for you on this but you're probably outta luck without buying the upgrade thing for the emote etc if it still exists.
