The keymap editor add-on does have that behavior unfortunately but in the case of configuring for CEC this is by far the easiest way to get working key id numbers because a) the Kodi log does not list key id’s and b) the key names for CEC are incorrect. I would just backup your current keymap/s, use keymap editor to find the key-id numbers, then use those to manually edit your existing keymap.
Alternatively...
Replace keymap on running system with this and via SSH kodi-send --action=reloadkeymaps
which of course will make your system unusable until you remove that and issue that action again.
