So there is a bug that heavily annoys me and many others
The defacto sound limit.
So when you have a few long enough sounds or enough smaller sounds, it decides to not save again.
This heavily annoys me when I'm making projects with many sounds (such as this music project https://scratch.mit.edu/projects/369759328).
This also often happens when I shorten a song (which means it will save with the longer song but not the shorter song, see the logic?). So i don;t know if this is a unfixable problem or its something you can do but please, just help.

The reason why it doesn't save the shorter song is because the original sound file is (most likely) in MP3, but when you edit a sound in Scratch (in any way), it is automatically converted to WAV, which takes up more space.
For your knowledge, the maximum sound file size is 10 MB and I don't think that the Scratch Team is planning to increase it, considering that the only way they make money is through donations.

I understand. But why is made wav? If it takes up more space, wouldnt it be impratical? I really don't understand sound editing so I get if its becuase thats the only way or something. Thanks.

There is no efficient way to save the edited sound as MP3. Yes it's possible, but it can be a huge performance issue.
