If your goal is to see if the building is in use, you can't do that in Member Tools. The only authoritative calendar for building activity is the location calendar. And that's only visable on churchofjesuschrist.org.
If you're referring to a ward or stake calendar, then there's a couple of things to check. First is to see what calendar you've selected on churchofjesuschrist.org. I believe that will determine what calendars get pushed to Member Tools. Of course, you'll have to do a sync if you've made any selection changes.
Then, in Member Tools. there's a filter in there as well. Go into the calendar, click on the three dot menu, then "Calendars to display".
