How do i use NoiseTexture2D for voxel world generation?

so I have this simple setup where upon generating a chunk, that chunk will get a noise texture from its parrent, offset the noise texture by its own position, and then apply a height to every block based on the value of the pixel corresponding to the position of that block within the chunk.
public async void GenerateChunk(){
NoiseTexture2D Nos = parent.Nt;
FastNoiseLite Fnl = (FastNoiseLite)Nos.Noise;
Fnl.Offset = new Vector3(Position.X, Position.Z, 0f);
await ToSignal(Nos, "changed");
Image IM = Nos.GetImage();
for (float x = 0f; x < 25f; x++){
for (float z = 0f; z < 25f; z++){
Color C = IM.GetPixel((int)x, (int)z);
float y = C.R / 0.05f;
BlockDict[new Vector3(x - 12f, Mathf.Snapped(y, 1f), z - 12f)] = 0000002000000;
if(x == 24f && z == 24f){
ChunkUpdate();
}
}
}
}

here is the NoiseTexture2D settings:

so the idea is that since each chunk is 25 by 25 blocks, we get a noise texture that is also 25 by 25, and then set the height of each block to the color value of the pixel in the same position in the texture. after that we add them in the BlockDict dictionary so that they appear in the game when we update the chunk. the reason we deduct 12 units from x and z is because the for loop will give us values from 0 to 24, reducing them by 12 will put every block between -12 and 12, which is the correct values for the borders of the chunk.

as you can see, the offset is set to be the chunks own position(since the noise is 2d, the z value of the chunk is equal to y on the noise, hence i put it there in the code.). from my testing, each unit in the offset moves the texture by 1 pixel, so 25 in the offset is 25 pixels along the noise and since the center of each chunk is 25 blocks apart, i chose that location as the offset for the noise.

the result isn't what i expected however:

there are weird gaps between the chunks and i have no clue why. i thought the noise's height would be more consistent than this.
i messed around with the settings a ton but it would always come out disconnected like this, my ideal settings would be that every block is only 3 blocks higher or lower than its neighbors. does anyone know how i can implement this?
