CEC "Ok" button doesn't work

  • Im using Odroid C2 with LE8 and CEC was working great connected to my TV.

    Now I got a new projector and CEC is buggy on this projector, all buttons (back button and directional) are working except OK button. But the funny thing is I can hear a GUI sound when pressing OK button just nothing happens...

    I have tried Keymap Editor to remap Enter to my OK button but the same thing happens..when I press to edit button I can hear GUI sound of my button presses but the addon doesnt detect my OK button..

    Now I have remaped my left directional button to Enter but this is really frustrating.

    Help please anybody if you know what I could do..
    I can hear the button working (making click sound in GUI) but it doesnt do anything (and cant be remapped) Sad
