Shaders Compiling each time i open the project

Total newbie trying to self teach.

My C drive was full so i did this:**
"Open BaseEngine.ini > UnrealEngineVersion\Engine\Config\BaseEngine.ini

Find: [InstalledDerivedDataBackendGraph]


to: Path=“%GAMEDIR%LocalDerivedDataCache”

All cache will be saved in to directory of your project"

but now the project is compiling each time i open it, i have 2 landscapes in my project and used the experimental water plugin. No foilage.

Thank you.
