Hello, @arun_97,
I just wanted to point a few things:
1. In the photo you send us, in the ID field, the email_id has an empty space, you might want to fix it as data elements are sensitive.
2. Instead of using the identityMap custom field, you might use custom code, in our investigations, we found that it works much better. It also gives you more flexibility. You might want to use it in the SetConsent rule alongside a Consent Custom Code that you can find in this documentation: https://experienceleague.adobe.com/en/docs/experience-platform/xdm/data-types/consents#prerequisites

Regarding the change of the name, sometimes, as the data is new to the platform, in this case the new name, AEP takes some time to update the UI in the audience builder. Luckily, by now, you have already solved this problem.
I hope this solved your problems.
