String errors: «himself»/«itself» and messy string

[Mathias Bynke]

These are the strings:
String 75: https://translations.launchpad.net/gui-ufw/gufw-13.10/+pots/gufw/nb/75/+translate
String 76: https://translations.launchpad.net/gui-ufw/gufw-13.10/+pots/gufw/nb/76/+translate

String 75 reads «Some rules are added by himself?».
This does not make much sense, perhaps it was meant to say «Some rules are added by themselves?»?
As a side note, I would also suggest «Why are some rules added by themselves?».

String 76 reads «Well, when you change or import a profile, or when you edit a rule, Gufw is re-adding that rule, then ufw is re-adding for IPv4 and IPv6, then this is the behavior.»
As a translator I am having trouble understanding what this means. I suggest that it be cleaned up.
