it does not show in game how do I find that it only has (MouseSensitiveName="Targeting",LastConvertedMouseSensitivity0.008944

The LastConvertedMouseSensitivity value is the actual sensitivity applied, while the MouseSensitivity value is the value in the menus.

So if you only set the LastConvertedMouseSensitivity value, the sensitivity will be correct, but in-game it will show 50. And if you change any sensitivity setting in-game it will reset the LastConvertedMouseSensitivity to reflect what you see in the menus.

So the trick is to calculate both values, just switch the Location selection to Config File 2 to calculate the MouseSensitivity value as well, and enter both values in the file where they belong.
