Issue mobsf security framework

I have an app in ionic that I am testing security with mobsf and I have the following issue ( is Protected by a permission, but the protection level of the permission should be checked.
Permission: android.permission.INSTALL_PACKAGES
[android: exported = true]

I modify the config.xml

    <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application/receiver" xmlns:tools="">
            <receiver android:enabled="true" android:exported="false" android:name="" android:permission="android.permission.INSTALL_PACKAGES" tools:replace="android:exported">
                    <action android:name="" />

but I keep getting the same error
