Reproduction Steps:
1. Open the attached project "ReproProjectGuoda.zip"
2. Create a new Material utilizing the URP/Lit Shader
3. With the material selected, navigate to the Inspector Window and click on the "Edit" button
4. In your IDE, Enter "SHADOWS_SOFT" in the search field
5. Carefully examine the prefix associated with the keyword.
Expected result: There should be a single underscore at the beginning of the keywords as shown
(#pragma multi_compile _SHADOWS_SOFT _SHADOWS_SOFT)
Actual result: There are two underscores at the beginning of the keywords
( #pragma multi_compile_fragment _ _SHADOWS_SOFT _SHADOWS_SOFT)
Reproducible with: 12.1.14 (2021.3.36f1), 14.0.10 (2022.3.22f1), 16.0.5 (2023.2.16f1), 17.0.2 (6000.0.0b13)
