This specific note keeps stretching but when i play it its fine?

I use both freesamp and moresampler but when i play this specific note 'u d' it has a strectching noise idk how to describe it, it's like a cv voicebank without an Oto
My voicebank is CVVC and monopitch, i think i oto'd the VC note correctly but i dont know if its correct im just a beginner

The portion in white is the area that will get stretched. To adjust this, you can move the fixed region (pink) and cutoff (right blue area)

I tried fixing the fixed region and cutoff so it sounds like "uddd" but the d sound is in the right place but the d still has a weird stretching sound

The lowercase s button in the OTO window will show the spectrogram for this audio file. This might make it easier to see the audio frequencies and figure out where to place the lines.
