Default Calendar App not syncing

[blackfyre]

I couldn't sync my online account calendar to my default calentar in xperia M. But when I install Google calendar from playstore it is showing both the device as well as the account calendar. 

The same is not working in the default calendar app. I tried to sync my online calendars but still the appointments and reminders of my online calendar is not showing up in my default device calendar.

Please help.

Hi, 

Try to clear data for calendar under settings > apps > all > calendar > clear data. Restart the phone and try again. 

Also make sure that you have selected your calendar as synced and shown under calendar > menu button > my calendars.
