Missing flights in the logbook MSFS 2020

Hello Simmer,
the last update was downloaded and installed without any problems.
After that, the entries about my last two flights are missing in my logbook.
I’m using LITTLE NAVMAP on a second monitor, which has not caused any problems so far.
Is there already a solution to the problem that I can carry out myself on MSFS?
Happy Flight
