Exporting as flac Windows 10, version 2.3.3

Hi everyone,
I have noticed as I exported a short project as flac, the sound was incomplete.
Exporting as mp3 was fine however.
I tried to report it on bugzilla but I could not get through recptcha.
The quality of the pictures is so bad that you have to guess half the time whether to click or not. :angry: :angry: :angry:
Plus, is there a time limit? It seems to me that after a short time this thing resets.
Kind regards,

In what way was it “incomplete”?
