Problem adding event to google calendar (from any app)

I have problem adding event to google calendar (from any calendar app, even its own app) form Le 1 Pro US(Rooted). Every time I try adding an event the phone keep sync it to google calendar multiple times and continue to do so every time it sync calendar(see the picture). It won't stop until I delete them all from the phone and google calendar. Not sure if this happened before it was rooted.
Anyone has this problem?
Any suggestion?
Should I try deleting and reinstall Calendar Storage and CalendarSyncAdpter?

Event for double tapping the recents button?

Basically, i'd like to be able to double tap my recents button (while using the phone one-handed) as an alternative to stretching my thumb way over to the back button (i've almost dropped the phone several times doing this). I'm not new to tasker and realize i may have to find some other solution, just thought maybe someone here would have a trick up their sleeve?

Where are default brightness values stored? (Event 85)

The purpose of this question is related to an intermittent problem that I experience on my Eonon with the Malaysk 444 rom, which results in the screen going blank. I suspect that it is "stuck" in auto brightness mode, and as a result some of the auto brightness values, for whatever reason, do not register for my device and result in a blank screen.

My temporary solution to this problem is to rekey a physical button using MTC-Keys as event 85 (event_44=85). This works to move the brightness value from 0 to 100% with a few steps in between. My results are that I go from 0% which is a blank screen, then get 25% brightness, then 50% results in a blank screen, then I see 75% and 100% as expected. Does anyone know where the predefined sequence values for event 85 are stored? I'd like to play with setting different brightness values (0-255) for the various steps to see if I can find values that work at each stage. I suspect this might fix the auto-brightness values as well.

Thanks in advance.
