[CLIENT] Option to hide offline friends is always unticked when client is opened

Whenever I open the client the option to hide offline friends is always unticked (meaning my friends list is flooded with all my offline friends). Three days ago before I was having this problem I unticked it myself so I could look at my friend's profile, after I was finished looking I hid offline friends and then went on to play a few games. The next day when I logged on my offline friends were showing again, even though I ticked the box to hide offline friends. This had happened every time I've logged after I unticked the box (about 4 or 5 times) and not once has it been ticked when I log on. Once I tick the hide offline friends box it is fine until I log off.
