MIUI backup skips a lot of apps!

[Elancore]

Hi, I tried to do a backup multiple times, it does it for some apps and skips the others, only about 5 of 40 are backed up (data + app) and the others only data is backed up, that happened when I upgraded to V5, before I was doing that successfully for all apps on V4.

MIUI V5 - GT-i9300
