Apps Script was only partially installed in my G Suite account.

I have no idea what that means.
I uninstalled it. Click UNINSTALL APP.

Uninstall App.

Make sure that you are sitting down, and that you have your seat belt fully fastened, then click CONTINUE.

The Apps Script add-on was re-installed. Click DONE.
Now that I have the Apps Script add-on fully installed, I have no idea what the difference is.
Does anyone know anything about this?
