TLS_Fallback on Windows Server 2012 R2

I have read articles which indicate that Windows Server does not support TLS_Fallback (ref https://community.qualys.com/thread/13956 and https://scotthelme.co.uk/getting-an-a-on-the-qualys-ssl-test-windows-edition/). We host many Windows servers and during a regular check, I found that each endpoint on one specific server indicates that TLS_Fallback_SCSV is supported. I have spoken with Microsoft who also indicated this was not something they have seen be configured on a Windows Server and I cannot figure out the difference between this box and other boxes which do not have this shown as supported on SSLLabs. Any ideas?
