My audio disapppeared

Why did all audio just disappeared after i synchronized my decks from anki web to my pc version of anki?
when i was reviewing them on (with?) phone they were there, everything was working correctly, but when i switched to pc they suddenly disappeared.
progress and other are saved correctly
what is odd that only audio for one deck was saved, and other decks’ audio wasn’t
does anybody know how to fix it?
Version of anki I’m using is 2.1.49
