Audio Distrubution Guidelines are Unbelievably Confusing

Not quite sure if this is the proper category for this, but I’ll give it a go. I’ve been trying to distribute sound effects on the platform, and I’m getting approximately a 30% success rate. All of them are getting accepted- but 70% of them are denied for distribution. All of them are classified as sound effects and they’re under ten seconds.

I originally wasn’t going to ask about this, but then I uploaded one

that got denied, and I was like, “alrighty, better luck next time”

Then, I uploaded this one

…which is nearly the exact same thing, and it was able to be distributed! What?

Can someone tell me why this is the case, and can someone tell me the guidelines my audios need to follow for distribution? I’m not talking about the basics like, the audio must be yours… I want the specifics, because this is really throwing me off.
