Keyboard-mess

Hello. I have been using a Logitech G15 keyboard with my MBP for years now without any problems. However, a few days ago my Mac have changed the following signs: < and > to ' and §

I have tried a lot of things, but nothing seems to work. The first image is the keyboard layout of my Mac. The second image shows my Logitech keyboard. Is there any way I can make the Logitech the same as my Mac keyboard?




Thanks in advance!

 

Code:

{
    AppleCurrencySymbol =     {
        smRoman = kr;
    };
    AppleCurrentKeyboardLayoutInputSourceID = "com.apple.keylayout.Norwegian";
    AppleDefaultAsciiInputSource =     {
        InputSourceKind = "Keyboard Layout";
        "KeyboardLayout ID" = 12;
        "KeyboardLayout Name" = Norwegian;
    };
    AppleDictationAutoEnable = 1;
    AppleEnabledInputSources =     (
                {
            "Bundle ID" = "com.apple.PressAndHold";
            InputSourceKind = "Non Keyboard Input Method";
        },
                {
            InputSourceKind = "Keyboard Layout";
            "KeyboardLayout ID" = 12;
            "KeyboardLayout Name" = Norwegian;
        }
    );
    AppleGlobalTextInputProperties =     {
        TextInputGlobalPropertyPerContextInput = 1;
    };
    AppleInputSourceHistory =     (
                {
            InputSourceKind = "Keyboard Layout";
            "KeyboardLayout ID" = 12;
            "KeyboardLayout Name" = Norwegian;
        },
                {
            InputSourceKind = "Keyboard Layout";
            "KeyboardLayout ID" = 252;
            "KeyboardLayout Name" = ABC;
        }
    );
    AppleItlbSort =     {
    };
    AppleSelectedInputSources =     (
                {
            InputSourceKind = "Keyboard Layout";
            "KeyboardLayout ID" = 12;
            "KeyboardLayout Name" = Norwegian;
        }
    );
    DisplayModeData544c4442 = "-197878996";
}

The same output applies to both keyboards.

 

The problem is with the Logitech Keyboard. The Mac keyboard is perfect. The layouts are identical, see images below.
