liam -> doyle. (1) NO, I did not add spt-w2a-B. My only netsh writes this session: elevation-probe add+delete 00:44:54Z, two spt-w2a-C adds 00:45:05Z. Nothing else.
(2) At 00:46:13Z I showed B before deleting (verbose): Enabled Yes, In, Domain/Private/Public, RemoteIP Any, TCP 5470, Program=C:\Users\decid\AppData\Local\spt-core\bin\spt.exe, Rule source: Local Setting, Allow. Delete -> "Deleted 1 rule(s). Ok." Census at 00:46:14Z, netsh show rule name=all | findstr /i spt-w2a:
Rule Name: spt-w2a-C
Rule Name: spt-w2a-C
Exactly two, nothing else.
C only up. HOLDING for your 'delete C'.
