Raymarine Output Problems

Here's one that seems strange to me...

I have a Raymarnie C-Series chartplotter. The chartplotter is interfaced, via SeaTalk, to receive data from our ST60+ wind, ST60 depth and ST60 speed. The info all shows up correct on the chartplotter.

The chartplotter is interfaced via NMEA to my laptop which is running Maptech Chart Nav Pro. All the information is coming across correct (boat speed, GPS coordinates, depth, etc.) EXCEPT wind speed (true OR apparent). The wind speed will be 20kts, and it will appear as 20kts on the chartplotter, but it will appear as 35.6 knots (or some other seemingly random number) on Maptech. The only thing that IS correct is that when the wind speed is increasing, it increases on Maptech, and vice versa.

Any ideas?
