First file not recorded

Hi, I'm trying to record full nights with some audiomoths, but the first files are not recorded. E.g., when I enter as recording time 19:50 - 07:30 (UTC+2), I get these files:

no file (recording from 19:50 till 22:13)

20240408_221310.WAV (recording from 22:13 till 0:36)

20240409_003620.WAV (recording from 0:36 till 2:59)

20240409_025930.WAV (recording from 2:59 till 5:22)

20240409_052240.WAV (recording from 5:22 till 7:30)

I tried this with several audiomoths and with time zone UTC and local time UTC+2, but they all gave the same problem. Last year, this all worked without problems. Only thing changed is that I flashed them to the newest version. What am I missing?
