Weird audio track bug

[Masked Stickman]

TL;DR: I can't play any additional audio on a specific audio track, but this doesn't affect the songs that were already there

In advance sorry if I don't explain myself clearly, English isn't my main language

While making a video, I downloaded a song as background music, it didn't played and I thought it was because it was an mp3 file so a converted it to a WAD, it still didn't played, I decided to play the song on the media preview and on a separate media player and I could hear the song without any problems, after some fiddling around, I changed the song to a different audio track and was able to finally hear it, I tried playing other audios on the broken audio track as a test and I couldn't hear anything, but I still could hear the songs that were already on the broken track just fine, is there anyway, should I worry about this bug? Is there any solution aside of changing audio tracks/making a new one or anyway to prevent it from happening again?

It doesn't make sense to me. The only track specific property I can image to cause it is muted track. Shown here:

it's not that because I can still hear any music that was already there
for example, in audio track 1, I add music 1 and I can hear it, I add music 2 and I cannot hear it but I can still hear music 1 but if I move music 2 to audio track 2 I can now hear it

Sorry, no idea then.
You can try to share screenshot and maybe I will be able to figure it out of the screenshot.
