[Spore] Creepy & Cute Pack: Store says Chinese, but DLC is English

The Issue:
The official EA store page for the "Creepy & Cute Parts Pack" DLC clearly lists Traditional Chinese as a supported language. However, after purchasing and installing it, all text for this DLC (item names, descriptions, etc.) appears in English. There is no Traditional Chinese text for any of the DLC content.

Important: This only affects the Creepy & Cute Pack.

• ✅ Base game Spore → Traditional Chinese works fine (via -locale:zh-tw)
• ✅ Expansion Galactic Adventures → Traditional Chinese also works
• ❌ Creepy & Cute Parts Pack → English only, no Traditional Chinese text

What I've Tried:

• Using -locale:zh-tw launch parameter → base game works, DLC still English
• Verifying game files in EA App → no change
• Reinstalling the DLC → no change
• Checking Data\Locale\zh-tw folder → folder exists, but DLC-specific text files appear to be missing

Screenshots (attached):

1. EA App store page showing "Traditional Chinese" support for this DLC
2. Base game menu (correct Traditional Chinese)
3. DLC item description (English, not garbled)

My Questions:

• Is this a known issue with the EA App version of this DLC?
• Does anyone know if the Traditional Chinese language files for the Creepy & Cute Pack actually exist somewhere?
• If the store page promises a feature that isn't delivered, how do I properly report this to EA so they can fix it?

Any help would be appreciated. Thanks!
