Make sure you've completely deleted the old contact with the name "My love." Double-check your contacts list and ensure there are no remnants of the old contact.
Sometimes, a simple reboot of your phone can help clear any temporary glitches or cached data that may be causing the issue.
Clear your call logs to ensure there are no references to the old contact with the "My love" name. The call logs might be showing the old contact name even if it's no longer in your contacts list.
If you're syncing your contacts with a cloud service or social media account, temporarily disable the sync feature, and then re-enable it. This can help refresh your contacts and ensure that the old information is not being pulled back in. On some devices, there might be a "Caller ID" or "Caller Name ID" setting that combines caller information from various sources. Make sure this setting is configured correctly and not causing the issue.
Ensure your phone's software is up to date. Manufacturers often release updates to fix bugs and improve overall performance.
