Another thing I just noticed is that this version of LE is not switching off the NUC when power off signal is beamed, because Shutdown Menu is popping up and NUC stays with it forever (hard to notice on a blank TV screen ).
This didn't help:

cp /usr/share/kodi/system/keymaps/keyboard.xml /storage/.kodi/userdata/keymaps/keyboard.xml
nano /storage/.kodi/userdata/keymaps/keyboard.xml
<power>ShutDown()</power>
<sleep>ShutDown()</sleep>
This seems to solve it:
