I can't get rid of the trail renderer overlapping?

Image 1 Trail Renderer Overlapping Problem

Image 2 - Trail Renderer color settings Trail Renderer color settings

My last shader:

  Shader "TrailWithZWrite" {
      Properties{
          _Color("Main Color", Color) = (1,1,1,0.5)
          _AlphaTex("Base (RGB) Trans (A)", 2D) = "white" {}
          //_ExtrusionAmount("Z Extrusion Amount", Float) = 0
      }
          SubShader{
              Tags{ "Queue" = "Transparent" "IgnoreProjector" = "True" "RenderType" = "Transparent" }
              LOD 100
  
              ZWrite On
              ZTest Less
              Blend SrcAlpha One
              //Offset 0, -5000
  
          Pass{
  
              CGPROGRAM
              #pragma vertex vert
              #pragma fragment frag
  
              #include "UnityCG.cginc"
  
              fixed4 _Color;
              sampler2D _AlphaTex;
              //float _ExtrusionAmount;
              float4 _AlphaTex_ST;
  
              struct v2f {
                  float4 pos : SV_POSITION;
                  half4 color : COLOR0;
                  float2 uv : TEXCOORD0;
              };
  
              v2f vert(appdata_full v)
              {
                  v2f o;
  
                  //float3 camDirObjSpace = normalize(ObjSpaceViewDir(v.vertex));
                  //v.vertex.xyz += _ExtrusionAmount * camDirObjSpace;
                  o.color = v.color;
  
                  o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
                  o.uv = TRANSFORM_TEX(v.texcoord, _AlphaTex);
                  return o;
              }
  
              fixed4 frag(v2f i) : SV_Target
              {
                  fixed4 texcol = tex2D(_AlphaTex, i.uv) * i.color;
                  return texcol * _Color;
              }
              ENDCG
          }
      }
      FallBack "Unlit/Transparent Cutout"
