Help! My Utau that i made does not work

[Pixelody Chiptune]

My UTAU that i made only sings on some notes but ignores most of them. I've recorded a whole hiragana reclist and it doesn't work.
Please help me!

What type of voicebank is it?

If there's a lot of extra space at the beginning of your recorded sounds and your bank isn't oto'ed sometimes it can make that happen?

Is oto'ing when you choose CV or VCV? I just clicked continue without changing anything execpt for the window type to Blackman.
And no, There isn't any space in the recordings. I've already learned not to do that from my first Utau and this is just a re-recorded version without any space

Otoing is the process of configuring your voicebank.

This might be able to help you.
