Jurisdictional officer detail missing from gst certificate

Sir,

Kindly give your valuable advise on 3 queries

1. My GST application got approved today but the registration certificated I downloaded from GST portal does not have any details about Jurisdictional officer like  - Signature, Name, Jurisdictional office . Please tell If we need to worry about it.

2, I registered under Composition scheme, In my GST account Taxpayer type is - Composition But in my downloaded registration certification Type of Registration is Regular . Is this correct ?

3 Also, I want to correct an error in place of business address, but there is no option . Kindly guide me about the process.

Thanks
