Object Repository is already exist and having all objects.
Example, my Object Repository has:

+ Object One
- abc$co12l
- abc$co12k

However, when create a new test by recording it adds same object to the Object Repository such as:

+ Object One_2
- abc$co12l
- abc$co12k

+ Object One
- abc$co12l
- abc$co12k

How can I stop QTP from adding objects which already exist, when record a new test?
