Hello HeYHeY1991,
We see you need help with your call history showing in opposite order to how it should. One step you could do that should help is to Reset All Settings on your iPhone.
Return iPhone settings to their defaults
- Go to Settings
> General > Transfer or Reset iPhone > Reset. - Choose Reset All Settings.
Note: All settings—including network settings, the keyboard dictionary, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
3. Enter your passcode.
You may want to create a backup of your iPhone before doing this step to protect settings data.
