Strange. It’s working fine for me.

Your picture of the FMC is showing that it is aligned.

I finally understand how bug is triggered. When you turn on battery and external power, if you switch the MCDU on POS INIT page before set IRS knobs to ALIGN and NAV, the SET IRS POS row doesn’t appear and you have to reload the flight. Instead if you turn on battery and external power and set first IRS knobs and then switch MCDU on POS INIT page the SET IRS POS row appear regularly on both MCDU. I would be grateful if someone can replicate this just as confirm
