Warning Message "SDK path collision for path"

I see this warning "SDK path collision for path.../Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS14.4.sdk'>': SDK with name 'iphoneos14.4' being superseded by SDK with 'iphoneos14.4'." on my build server, any idea what causes this?
