Hi JLMCOO,
Thanks for reaching out in Apple Support Communities. I understand that the names of voice memos on your iPhone are skipping in chronological order even though there isn't a recording with the missing number in the title. I can see why you'd reach out about this; I'd like to help. I'd recommend using the steps below to troubleshoot this behavior:
Take some time to test for the behavior and if it continues, first create a backup: How to back up your iPhone, iPad, and iPod touch
Then use these steps to remove and reinstall the Voice Memos app and test again for the behavior:
- On your iOS device, touch and hold the app lightly until it jiggles. If the app doesn't jiggle, make sure that you're not pressing too hard.
- Tap on the app, then tap Delete.
- Press the Home button to finish.
If you have an Apple Watch, deleting an app from your iPhone also deletes that app from your Apple Watch.
- On your iOS device, go to the App Store.
- Search for the app. Make sure that you use the exact name of the app. Find the correct name of built-in apps.
- Tap to restore the app.
- Wait for the app to restore, then open it from your Home screen.
If you have an Apple Watch, restoring an app to your iPhone also restores that app to your Apple Watch."
Delete built-in Apple apps on your iOS 12 or later device or Apple Watch
Let me know what you find.
Best Regards.
