Rename Operation Issue - ApacheDS

Whenever we perform Rename operation on an object entry (let’s say Person object), the person gets renamed successfully but the issue is that the old value of the person object still remains.
The ‘cn’ attribute contains two values now - old value and also the new value.

Example:
I have created a person object with DN "cn=person,ou=Apache,dc=example,dc=com" and I want to rename this entry to "cn=person_Rename,ou=Apache,dc=example,dc=com".
The rename operation executes successfully and the person is renamed to "cn=person_Rename,ou=Apache,dc=example,dc=com".
But, the ‘cn’ attribute now contains
“person”
“person_Rename”.

When verified the schema, ‘cn’ attribute show as ‘single valued’ but after performing the rename operation – the ‘cn’ becomes ‘multi-valued’ and contains two values.
This an issue with Apache directory which needs to be resolved. Also find the screenshots attached for your reference. Please look into the same.
