When you configure Log Redaction to "Yes" it is only redacted if the header is sent on the exact same case as seen on Service Studio. It should have been case insensitive as RFC 7230 Section 3.2 states:
Each header field consists of a case-insensitive field name followed by a colon (":"), optional leading whitespace, the field value, and optional trailing whitespace.




This behavior happens with or without Name in Request set.
