Muted audio in imovie plays in exported movie

Hi,

I'm using the latest version of imovie for IOS (2.2.1) and i've issue with the movies exported

I've muted all sound from clips in imovie.

When I export my movie ( it doesn't matter how I do it, i've tried all the export options) the clip audio is playing (whereas it is on mute) and not on the correct clips, like there is a background track of audio from other clips...

I cannot see the audio, I've detached and deleted all audio, i've muted it multiple times, it doesn't play the audio in imovie just when I export it
