iOS 12 Calendar integration to 3rd Applications

Hi after updating to iOS 12 I seem to have all 3rd party app integration to Calendar disappear.

I have airwatch profile installed for device management as its part of my work requirements.

Images attached are from iOS 11.4 where everything was working and the last one from iOS 12 where the calendar integration is missing.

Has anyone else have any issues Like this? Note that I’m using exchange sync for my calendar in the setting apps.
