Titanfall Ultimate Edition bundle contains deluxe content that is not available

[WantingL]

 I bought the included content in Titan fall Ultimate Edition, but it doesn't work in the game. The content of the included bundle is shown as expired in the game store, and clicking on it doesn't respond. There is no way to equip my characters or Titans with skins.My Steam store is located in China. The games purchased are also in Chinese. It is in traditional Chinese.Are there any solutions? Thanks
