The issue where only non-English languages appear when adding a second birthday to contacts on your iPhone is likely a bug or a localization issue that Apple needs to address. This problem has been reported by multiple users over the years. Unfortunately, as an individual user, there's no direct way to fix this bug permanently. However, you can try the following troubleshooting steps:
1. Check Language and Region Settings:
- Go to Settings > General > Language & Region.
- Ensure your preferred language (e.g., English) is set as the primary language.
- Make sure the region is set correctly.
2. Restart Your iPhone:
- Sometimes, a simple restart can resolve temporary glitches.
3. Update iOS:
- Ensure your iPhone is running the latest version of iOS. Go to Settings > General > Software Update.
4. Reset Keyboard Dictionary:
- Go to Settings > General > Reset > Reset Keyboard Dictionary. This might help if the issue is related to keyboard settings.
5. Contact Apple Support:
- If the problem persists, consider reaching out to Apple Support. They might have additional solutions or be able to escalate the issue.
These steps might not resolve the issue if it's a deeper bug in iOS, but they are worth trying. For a long-term solution, continued feedback to Apple might prompt them to address the bug in future updates.
