3371670 - Error: "At least one Customer Role required to maintain Additional Information" Upon Trying to Extend an Existing Supplier as Customer

After the 2308CE upgrade, using the app Manage Customer Master Data, when you try to extend an existing Supplier as Customer, the system throws the error:
At least one Customer Role required to maintain Additional Information

However, it is possible to extend an existing Customer as a Supplier with the app Manage Supplier Master Data. Further, with the apps Maintain Business Partner/Manage Business Partner Master Data there are no issues.
