Mystery signals?
Image icon 6M AURORA.JPG181.41 KB

Last evening before bed,observed that the auroral oval was growing quite large and expected 6 meter band activity.I had left WSPR running through the night.However,a local station was also using 6m WSPR and his signal clearly shows on the waterfall.However,he does not show as heard in my WSPR program window,no data and same for the map.
Just now returned to the radio and computer to find 2 stations on the WSPR program Window,neither are listed on or the WSPR map.
Does anyone know what this may be and why they are not logging?
See screenshot attached.
