What calendar are these events on?
On website, check the sync settings you are using. You might have set the sync to only sync some calendars. Also check your Member Tools app as it can also filter the calendar(s).
Lastly, be aware that events on the building calendar doesn't sync. If someone has placed events there, or if there's events from other wards, they won't sync to your phone. For that reason, you can't use Member Tools to see if a building is available. For that, you have to go to the website and look at the location calendar.
