**Describe the bug / 描述你遇到的Bug** If two or more groups with partially identical names exist, the second and subsequent groups do not work. **To Reproduce / 复现步骤** 1. Declare following ShaderProperties in the shader. ```hlsl Properties { [Main(Group_Color, _, off, off)] _groupColor ("カラー設定", float) = 1 [Sub(Group_Color)] _Stencil ("Stencil", Int) = 0 [Main(Group_ColorSettings, _, off, off)] _groupColorVariation ("カラバリ設定", float) = 1 [Sub(Group_ColorSettings)] _MainTex ("Texture", 2D) = "white" {} } ``` 2. When I click on the second fold, the SubDrawer does not appear.
