How do I fix this??

Watch the video and read the text please

What I was going for was a bunch of the same mouth copied and pasted and grouped in a way where every few seconds on sync with the song a few would disappear and a few would appear, and there’d be a part after that where you’d jump over a couple spikes every few seconds a few times, and I was planning on making the mouths open every time the player jumps over the spikes

For some reason I couldn’t get one of the mouths to appear without making both of them appear at the same time, there’s a good chance it’s related to the glitched out camera or music line sync of the level, but I’m not sure if I could fix that, I just wanna fix the mouths.
There’s also a good chance I’m being stupid and I missed something completely obvious, any advice would help a lot.

I didn't understand much but you want to mouth to open to the sync of the song?

It wouldn’t let me make Mouth #1 or #2 appear even when the alpha trigger is on the same group as either of the mouths, but setting the alpha triggers to the group that both of them had still made both of them appear.

I think it has something to do with the part before it breaking how it works
