Shader Offset not working

Hey guys,

So i'm working on a drag and drop ship building system, and created my own translate and rotate gizmos to use in game. I used the GUI text shaders since ZWrite is set to Off on that shader, and thus will always be rendered. The issue I'm having, is I'm using a modified toon shader to deal with selection highlighting in game, but this is being drawn over my translate and rotate gizmo, even with ZWrite being turned on. Here's a screen shot with the white box showing where the gizmo is not being drawn over the selected object.

Here's the code for the shader

 Shader "Outlined/Silhouetted Bumped Diffuse" 
 {
     Properties 
     {
         _Color ("Main Color", Color) = (.5,.5,.5,1)
         _OutlineColor ("Outline Color", Color) = (0,0,0,1)
         _Outline ("Outline width", Range (0.0, 0.03)) = .005
         _MainTex ("Base (RGB)", 2D) = "white" { }
         _BumpMap ("Bumpmap", 2D) = "bump" {}
     }

 #include "UnityCG.cginc"
  
 struct appdata 
 {
     float4 vertex : POSITION;
     float3 normal : NORMAL;
 };
  
 struct v2f 
 {
     float4 pos : POSITION;
     float4 color : COLOR;
 };
  
 uniform float _Outline;
 uniform float4 _OutlineColor;
  
 v2f vert(appdata v) 
 {
     // just make a copy of incoming vertex data but scaled according to normal direction
     v2f o;
     o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
  
     float3 norm   = mul ((float3x3)UNITY_MATRIX_IT_MV, v.normal);
     float2 offset = TransformViewToProjection(norm.xy);
  
     o.pos.xy += offset * o.pos.z * _Outline;
     o.color = _OutlineColor;
     return o;
 }
 ENDCG

     }
  
     Fallback "Outlined/Silhouetted Diffuse"
 }
 

Any ideas why it isnt working?
