[Problem] Candy5 LG G3 D855

I'm a new user and searched similar threads...
So, I installed Candy5 last weekend and I liked that room, faster and pretty nice, but now is starting some problems. When I restart the device, I lose all my configs, icons on homescreen disappear and my keyboard config also lost. Other point is, double tap to sleep doesn't work.
Some one had those problems too? Or knows how cand I fix that?

sorry if something iswrong.
