dashT streamout wrong Latitude/Longitude

Dear community,
I'm new here, so first a little introduction.
I've been using a raspi3b, raspi4-4gb and since June the raspi5-8gb now with openplotter-v4-headless.
In front of it is a Shipmodule-Miniplex-3wi that brings nmea0183 and seatalk-1 to nmea2000 and into WiFi.
Opencpn receives the data stream via tcp/ip or usb. Both work.
I started this to collect polar data with opencpn and the Polar plugin and to create my own polar diagram.
Later on vacation trips I automatically created a logbook with what was then still Logbook-Konni and logged VDR data.

Now my problem.
When I'm sailing in a regatta I want to collect all the data and later evaluate it with influxdb/grafana.
For this I activated DashboardTactics 1.7.61.
The streamout was only written after I created /usr/share/opencpn/plugins/dashboard_tactics_pi/data and
copied the .local/share/opencpn/plugins/dashboard_tactics_pi/data/streamin_sk_template.json and streamout_template* there.
I hope that was right?!
In the streamout I now always have the wrong but exactly the same values for latitude and longitude.
They change slightly but are always the same. So latitude=longitude.
The error can be reproduced using VDR on the raspi5.
Everything is OK in Windows with opencpn.
What do you need to narrow down the error?

Best regards and thanks

you could try signalk to do everything instead of going through opencpn first, it has plugins to save data to influx, generally best to let signalk do everything then just have opencpn getting data from signalk.
