When the in/etc/wfb.yaml is set to router: mavfwd, the mobile end cannot receive OSD information

[suiaiyun]

As the title suggests, when setting the Mavlink v1 or v2 for the flight control serial port, the OpenIPC data transmission interface can receive data from the flight control, but PixelPilot cannot display OSD information. Do you know the reason for this?

telemetry:
router: mavfwd
serial: ttyS2
osd_fps: 20
