[MSFS2024] Airbus A321LR

I’ve been experiencing a lot of hassle with this bird this evening. Yesterday was fine and I completed two short-haul IFR flights with zero problems. But today after entering the flightplan from the EFB, on the F-Plan page, I’ve noticed load of my waypoints have dissapeared. I only noticed this during the climb out when the plane stops following the magenta flight path and continues in a straight line. Yes, I selected IFR from the EFB drop down.

I’ve tried different destinations too and different SIDs but all the F-Plan page shows is the departure, sid t/c, t/d, star and arrival. None of the waypoints in between.The EFB still shows the full flightplan and yes it’s been submitted to the ATC and avionics. As it all worked yesterday, I’m assuming this is a ME problem.

Is this happening for anybody else or could anybody suggest what I may be doing wrong?

Thank you.
