PMDG 777-200 ER and Autobrake

[speedbrake1]

Hello,
I have a question about the PMDG 777-200 ER. I am in MSFS 2024 SU 2 and when I do a longer flight I always save snapshots. After loading everything works normally. The aircraft is configured for landing with Autobrake 2. When pressing the brake for 3 seconds to take over, the brake deactivates and switches back again, i.e. normal procedure.
When the landing gear is extended, however, the automatic brake switches off and cannot be reactivated.
However, this only happens when flying with snapshot, during landing training I can operate the landing gear and the automatic brake as normal.
I have no bindings for this brake in my hardware and only operate it with the mouse.
With the PMDG 777-300ER in MSFS 2020 this worked without any problems.
What am I doing wrong?

Supplement
It works in the MSFS 2020. I have just made the same flight with the same aircraft and used the snapshot and SLEW function in the same way.

One more addition:
It works again!
Perhaps the PMDG update yesterday helped a little.
