Error writing to FbDatalogger file

I ran into this problem. I write to a file using FbDatalogger. He didn’t record the data correctly. After rewriting the firmware in the PLC, the problem went away. Why does this happen?
bDatalogger_type = 3. Below I’ll provide a couple screenshots of different content. The program code has not been changed.
The correct data to be recorded:
2024-07-02_13-07-24

Data that was wrong:
2024-07-02_13-07-37

As you can see there is something wrong with the clock format and it only writes one post instead of 3 posts
