After Japan updating, some errors sensed

Hi, folks!
After Japan updating, My flight log menu doesn’t work correctly.
Some flight logs were missed or not recorded constantly when I checked the menu-flight log after finished a each flight.
Moreover every time I tried to “Tour of Japan”, the flight plan on a flight computer map screen is wrong. What’s going on this?
Is it some kind of bugs or error?
How can I fix it or you can check my status?
