Cannot change input key setting

Hi,

wanted to change some of my input keys, but I can only do this for mouse richt middle left.
When I open input screen a message comes 'One or more actions not set'. Unset key is Enable corpse targeting.
When I left-click on any line it will highlight and it shows 'press a key or mouse button..' but it won't change.
Even if I change to 'Reset to default' (without saving) it does not change anything, except mouse keys.
Can you please help me?

You can try to rename production_Config.ini located in %USERPROFILE%\Documents\My Games\Path of Exil folder then launch the game to recreate this file with default settings. Note that you will have to re-select all you personal settings in game Options as they all reset to their default values after that.

I renamed production_Config.ini but still cannot change anything except mouse keys.
