Audio playback issue

Idk why the audio doesn't longer play the same way : It's supposed to play from start to finish but around 6 seconds there is a small cut which then causes the audio to replay from the start even though I haven't split or anything other than lowering the volume, and the audio is not played completely until the end. I deleted and imported the audio again but it still remains the same. I haven't encountered this problem before until now and I'm currently trying to serach how to fix it
(What's circled in red is where the audio replays at the beginning even though it's supposed to be continuous audio)
