New Htc one s ville miui v5 3.11.15 Calendar/lockscreen bug

Feb 18, 2012
Hi guys, i did a clean install of the latest version and i have two issues on my htc one s

1)lockscreen is chinese
2)system calendar has a bug and instead of day names it shows numbers... So instead of sun, mon, tue, wed etc it shows 1,2,3,4....
Also pure Calendar widget stopped working!

I tried wiping and reflashing and still same issue. Please help!
