My Usts aren't coming out right

[Underlapped]

So I've been trying to make my own usts for a while, but everytime I try to actually use them, some issues arise
I'll try to explain but it is a bit difficult to explain
so, on word endings like "ai" "ei" "en" "un" etc, etc, it sounds really strange? and usually I'd attribute that to some problems with the oto that need adjustments, but I've tried using different popular utaus with my usts as well and it still happens
I've also fit the utaus to the ust as well and that hasn't worked either
here's an example



does anyone know what im doing wrong?

When editing the note properties, make sure that the Modulation is set to 0. If the box is blank, you will need to manually type the number 0 into it.

Ahhh that worked!!! I can't believe it was such an easy fix!!! Thank you so much Kiyoteru!
