Default [Q] Bluetooth and Calendar Issues In Kitkat

I have tried a few of the Kitkat Roms that are out there and have come up with the same issue every time. I am not sure if these are related but i am now at the stage where i think I will be stuck on stock forever -(

1. Email and Contacts sync (EAS) but my calendar does not
2. If I use a Caldav client the calendar works fine
3. Contacts are not synced to my Bluetooth in my car but the phone works
4. I have had periodic messages that the bluetooth share has stopped working and am then lose my bluetooth connection in the car

I think my pebble might have something to do with this as well but cant pinpoint it.

I have tried:
1. CWM/TWRP to flash the ROMs,
2. ODIN to stock then flash
3. Always wiping and clearing the cache prior to installing any roms

And still the same result. Googling has come up with some ideas but they dont seem to work.

Any help or thoughts would be appreciated
