I've a suggestion to simplify the config, otherwise works fine

I don't think you need all the disabled target_bundles_drag_drop items; they are referencing paragraph types that may not exist.

I suggest removing all the items with enabled: false, shortening this to

    target_bundles_drag_drop:
      localgov_banner_primary:
        weight: 0
        enabled: true
      localgov_banner_secondary:
        weight: 1
        enabled: true

Just found something slightly strange with this. A Secondary Banner paragraph is added to the form when creating a new page and this looks a little odd (particularly at medium screen widths).

There is another PR removing the secondary banner as the default option

#223

also contains some other improvements.

I've made those improvements @stephen-cox
