My tiktok sound links itself to the wrong song

Hey guys. Im a new artist, and im still learning how to use tiktok and other platforms properly.

For my first songs promotion, i screenrecorded the audio file and then created a tiktok where the sound was created. Then i used this sound on my tiktoks. The song later released and then was correctly connected with the tiktok sound i created.

Now when i am trying to create a tiktok sound for my second song, the song for some reason connects to a random song that doesnt resemble my song at all.

Ive tried contacting tiktok, but the AI bullshit is completely useless. I also tried adding a little pause before the song starts but it still links to the wrong song. I want it to not link to anything, except for my song when it finally releases on release day.

Any ways to fix this?
