That's normal, UTAU temporarily saves rendered notes in a .cache folder. They should be deleted when you close the program

Those files are .cache that are generated whenever you play something in Utau. You usually just have to delete them manually if you want them gone

(You can also search .cache files on your laptop and put them in the trash that way)
