Whisper sometimes randomly skip sentence

When we create transcription using Whisper API we encountered weird error. Sometimes (handful times in an hour of audio) there is skipped sentence. Timing of previous and next sentence is adjusted to cover missing sentence without gap. Previous sentence is wrongly timed few seconds longer. Following sentence starts a few seconds earlier. When we run same file again errors appear on different places.

Does anybody else encountered this error?

This skipping happens to me quite often and usually when the speaker I am transcribing is quoting something, almost as if Whisper is avoiding potential plagiarism or copyright or some such thing.
