depth mask braking lighting

Hello I lately copied and used a basic depth mask shader to cut a hole in a terrain, however there are some bugs now.

shadows are being cast on my depth mask ,clearly shadows should not be on a big hole of nothing.
lighting on any thing behind the depth mask is broken , no shadows are being cast and transparent objects are invisable.

here is my depth mask shader :

 Shader "Custom/depth mask" {
     SubShader{
         Tags{ "Queue" = "Geometry+10" } // earlier = hides stuff later in queue
         Lighting Off
         ZTest LEqual
         ZWrite On
         ColorMask 0
         Pass{}
     }
 }

thanks for reading , sorry for bad spelling ,thanks in advance for answers
