Google Calendar stopped working after flashing the November 17th build

Hi everyone,
I have an Asus Zenfone 2 (Z00D), yesterday I have flashed the November 17th build for the device, only to find the Google Calendar app no longer works. I tried checking the date & time of the device, it does seem to shows up correctly on the Date & Time settings, Timestamps, everything but the Data Usage page that shows date January 1st in 1970. So what should I do so solve my problem?
Thank you in advances
