Database Error ChaName

[SyntaxError]

Hi, I Am Trying To Make The ChaName Primary Key and I Receive This Error

" 'ChaInfo' table
- Unable to create index 'PK_ChaInfo'.
The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.ChaInfo' and the index name 'PK_ChaInfo'. The duplicate key value is (_GuNnEr_05).
Could not create constraint. See previous errors.
The statement has been terminated."

anyone knows how to solve this?
