music creation in system storage

I don't do anything with music or apps to make it. The problem is that on my Mac the music creation section is only shown within the first seconds after opening the storage management window, when it is still calculating the size of each section. Then it disappears and I guess that the music creation section content is just considered System Data, since that one section as a really huge size, but I can't delete anything from there unfortunately. What should I do to get the music creation section to be shown in the storage management window? Is there a way to look further into this?
