I see, but the gauges are not present in the VC because the 3 entries in the panel.cfg are wrong.

Do you have the airspeed, altimeter and radaralt on the CoPilots side from the beginning?

The correct fix should look like this, but it doesn't matter, it's all the same  ;)

gauge02=Captain_Sim.p721.L04!R04_airspeed, 275, 30, 177, 169
gauge04=Captain_Sim.p721.L10!R10_altimeter, 275,270, 210,240
gauge06=Captain_Sim.p721.L13!R13_ra, 260,505, 240,240

Simply replace the "R" with an "L".
