Xperia V require root permissions every time I have Xperia V 9.1.A.1.140 and I just rooted it using "Root Many Android" (see closer decription on XDA), and now I installed Titanium Backup and every time the app loads it requires permissions multiple times and every time I try to uninstall and app, why is that?

EDIT: And here is the solution - I also rooted it with motochopper (again described at XDA) which installs the SuperSU, and in now only asks the SuperSU for permissions only once and it's working fine now.
So here is what I did:
First I tried Bin4ry method's from XDA
with the 3rd option, it installs Superuser, but its buggy and it doesn't remember the permissions.

So then I did it with Motochopper method from XDA 
which installs SuperSU, and the root apps now require permissions from SuperSU just once, and it's working fine. 

After that I safely deleted Superuser.
