Problem of Google Calendar Add URL does not work

Problem of copying the URL in Syc calendar to Google Mail, Adroid, iPhone, and iPad does not work. We get a whole lot more that just the one calendar. We are getting a lot of ward calendars items as well as the stake calendar. We have only selected the one stake calendar and inactivated all others but still get the stake calendar and many other ward calendars.

First, make sure you're working from the right place: from the main lds calendar page, click on Settings > Subscriptions. Then click on the "All Calendars" tab.

This is where subscription is set up. Unchecking items in the main page only affects the main page display, not the subscriptions.

When synchronizing the LDS.org calendar all subscribed calendars will be synchronized. As RussellHltn has explained, deselecting calendars from the calendar view page will not unsubscribe a calendar but only remove it from view. Follow the steps to unsubscribe to have those unwanted calendars removed from the calendar sync.
