OSD Extended Link Stats and Mavlink ELRS

Hi all,

I have compiled firmware with OSD_EXTENDED_LINK_STATS param. I have set up RC via Mavlink ELRS according to this documentation: MAVLink - ExpressLRS. And now I see that RSSI dbm and LQ OSD widgets have dashes instead of values.

Same in 4.6.3.

Is it a known issue?
