Steps to reproduce:
- add a person "misty" with the contact details shown in the screenshot
- add another person "Misty" (same name but with different caps) with the same contact details in the screenshot.
Both "misty" and "Misty" are likely to be the same person, it could be user typo in this case. The user guide didn't mention that names are case-sensitive or case-insensitive. Maybe letting names to be case-insensitive and checking all the other details could fix this problem.
