Subordinate CA Cert Validity Period Issue

I am trying to setup a subordinate CA in our environment to our existing root CA. The current root CA cert is valid for 22 years (issued in 2019, valid till 2041). On the subordinate CA, I want the validity of that CA cert to be 10 years, and issue certs to clients for a maximum of 5 year validity.

I have verified that the root CA validity period is set for 10 years in the registry.

However, whenever I create the request for the CA cert from the subordinate and issue it from the root, it is always only for 5 years.

I have tried resetting the registry entries on the root CA and restarting services, removing the sub CA role and then re-adding, but nothing seems to resolve the issue where the sub CA cert is only for 5 years. I did notice that in the root CA, there is a template for "Subordinate Certification Authority" that has a validity of 5 years, but that is a default template I cannot change. If I remove that template then the Sub CA is not issued a cert as I get the error that the root doesn't support the cert requested. If I copy that template and change the copy period to 10 years and issue that, I still get the message that the request is for an unsupported cert.
