Button's on kodi doesn't work

I recently installed coreelec in a box amlogic S905 (K1 plus combo) and after doing the installation successfully, everything seems to work fine, but what happens is that if I do not play in the box I can not load any button in the kodi, I tried the box IR command and the minix airmouse A1 and I can play the mouse but I can not select any option, the sound appears to have loaded but does not load either the kodi button. After restarting the box everything works again until I again stop the box for a few minutes.

Sorry for my English, it’s not the best.

Thank you very much,
Best regards.

I have the same problems!

Skin works with win 10,Android. Only coreelec and libreelec the buttons doesnt work! Gui sounds ok. I cant see the buttons @osd player. Only this is the problem, rest works fine
