Time Setup issue in Digital Clock

Dear All,
In our application, we are using a control to set the time in digital format. I’m using sendkeys method to set the time. But getting a special character in the hour field(refer the attached snapshot) after setting the time. I have tried setValue method also. The value is getting passed, but I’m unable to delete the previous values in this field using that method. Also, the developer has used numeric field to set the values.

Do anyone know how to resolve this issue?
