Logitech Extreme Pro 3D

Why can't I bind certain keys on my keyboard? Specifically: Insert and Delete. My other key-binding issue is the Back-space key being permanantly binded to the Battlelog tab in the menu? Furthermore, that key (Back space) is also permanantly binded to Joystick 11 which also opens the Battlelog tab in the menue. I don't understand this because there are several tabs in the menue that seem just as important - six in all-Battlelog, Friends, Missions, Soldier, Reports and Leaderboards - Yet Battlelog is the only tab i've found to be 'perma-bound'. Puzzling. Joystick 11 is the one I use to exit air vehicles in a hurry.  It is perfectly placed for my prefference. Insert and Delete, I always used hose keys for VOIP and Spot/Communicate respectively. Also, Ican bind Back space and Joystick 11 to whatever I choose (rightly so) and they are useless because when I exit the Flaming hulk of scrap, that was a stealth jet just a second earlier, I am now in a menue and I have to exit that menue to pull the ripcord on my parachute. SPLAT! Insert and Delete don't bind at all. It's as if they don't exhist. Does this make sense for some reason I'm unaware of? Does anyone else have any other weird key binding issues?

Please and thank you!

Yes my graphics suck but can we just stick to the subject about the keybindings?

Any help is appreciated.
