Strange buzzing noise in audio made using Vital

So basically i am making a random note track using the White Noise thingy in Vital and sometimes the note is a buzzing noise that is not included in the sample at all. It must be some bug. Any explanation for it? Here is the audio file: https://drive.google.com/file/d/1-aEMXlTdiy2CQEOcisfyQwnGC0I2Hwcz/view?usp=sharing
