@tomlowenthal Should we have shield settings have its own listing here instead of bundling it with site settings?

There's already a bug (from Tom) for that (#3926) and if we decided to do that then we wouldn't have to fix the incorrect count.

Closing this in favor of #3926. Let me know if that doesn't seem right.
