OCPN receiving incorrect Apparent Wind Angle

Hi
I run OCPN on Raspberry Pi
My Nav instruments are Raymarine ST60 and connected to the Pi using the Raymarine SeaTalk-NMEA converter.
In OCPN I see an apparent wind angle from the wrong side. ie the value is correct eg 150 Deg but from the wrong side. It is actually incorrect in the VWR sentence that OCPN is receiving ie the sentence contains "R" when there should be an "L".
FWIW The wind IS displayed correctly on my ST60 wind display.

Any ideas ?

I think ive seen this posted before but a forum search didn't find anything

Thanks
Steve

Update it isn't simply L&R that are wrong. Wind has shifted slightly and noIve got in incorrect angle but correct side.

Could we see some screenshots, and especially some capture of your NMEA data stream?

Thanks
Dave

He also asked for a file of your nmea data stream. If you can send that alone, it would be helpful. Attach to here under "Advanced" adding an extension of *.doc or *.pdf because of file size.

For the screenshot you could take a cell phone picture, or digital camera picture.
