Logging Issue with Pixhawk 4, Copter 3.6.8

Hello dear friends,

I have a big issue about my pixhawk 4 that has 3.6.8 firmware version.

I tried to download dataflashlogs via mission planner. After that, Log was listed. I saw log which has that name 1/1/1980 01:40:53. I downloaded it. Then, I checked my data log list again. Pixhawk found new one log that have same name. They generated new log that has size of how many logs I downloaded times.

Could you help me, please?

Best Regards
